Windows Media Center Windows 7 64-bit Free Download

Anyone try I am but having other problems atm. I mean uninstall all mvk codecs aka cccp etc. Seems like a lot of work for possibly the same thing. I have networks shares working in win 7 right now. knock on wood.
I would say that playing the MKV file on the Windows 7 box (which is what the registry modification enabled) and allowing Windows Media Center to stream an MKV file are two very different tasks. You may need to use a different streaming server. There are more than a couple listed here ( -how-to-choose-dlna-media-server-windows-mac-os-x-or-linux), but I have only tried TVersity (though it seems to work reasonably well for this).
right, I had no problem playing mkv on WMP. Agree with oyu 100%. I think streaming through WMP is the issue in this thread. Other media servers would be benificial thanks and may solve for now. BTW playon works great
I think you mean Windows Media Center rather than WMP. Different animals. I believe Media Center tries to transcode the video to another format before sending it, while a network share just gives the file to WDTV Live and lets it figure out what to do with it. But nobody has confirmed this yet.
During Live tv some channels like HBO or AMC seem to stutter pause, audio becomes out of sync and generally jumpy and un watchable. There was a Flashing that occurred with the stutter but turning off the automatic contrast seems to have solved that problem.
I have done a lot of research on the issue and some call it a 29/59 frame rate issue. Most people though are able to alleviate the problem simply by turning off the adaptive contrast control. Others have given up and simply buy an additional graphics card.
Speaking of the drivers, included with the graphics driver is the Audio driver to take the audio over the HDMI cable. When the system goes to sleep however that driver seems to crash during wakeup and a reboot is needed to get audio back on the HDMI cable.
This has been reported as an application bug by Microsoft in KB_2658140. A case was opened internally to investigate if we could work around this bug via the Intel graphics driver. The investigation determined that due to the nature of this issue a workaround in the Intel graphics driver is technically unfeasible.
There is a flicker/stutter during premium channel playback which has been determined as being affected by the "Advanced Contrast Enhancement" or ACE feature. To be clear, this is different than the WMC app bug mentioned above which Intel cannot work around in our driver. To work around this ACE issue, please disable ACE in the CUI when experiencing this issue by going to Video>Advanced>Color Enhancement>Disable.
I am also having a similar stuttering problem. I am running the onboard intel graphics with a Gigabyte GA-Z87X-UD3H MB. The stuttering occurred some time back and I was able to fix the problem with the mentioned disabling of the auto contrast. Unfortunately, now that is disabled and the stuttering has returned while watching video/shows in windows media center.
I have the latest BIOS update from Lenovo installed (as of March 27th, I believe). FYI, this DID fix the problem of the yellow triangle issue on HDMI audio after turning my screen off and back on, but obviously, it did not fix the frame corruption.
A very important point that I think is CRITICAL to further investigate is that the problem seems to only affect HD channels that contain MORE than two audio channels in the signal, i.e. all 6 channel audio stations stutter for me to some extent. For me, NBC with 6 channels only gets corrupt frames every few minutes, but ABC and CBS do so constantly, so it varies in severity. On Ion television, in contrast, with only 2 audio channels, it doesn't show the problem.
Elsewhere on the Web, over the years, people have referred to similar problems to this in Windows Media Center where Live TV will display: checkerboard artifacts, block artifacts, glitches, stuttering, corrupt frames, etc. I've read that AMD graphics drivers have also at times caused such problems. However, what people are currently experiencing might or might not be the same thing. Some people that I've read in the past have had a similar problem that traced back to a Vista SP1 update that Microsoft made regarding msmpeg2vdec.dll, but I don't think that applies in this current case, as I've tested alternative video decoders and have seen the same problem.
For explicit evidence of the frame corruption, type 411 while in Live TV in Windows Media Center, then hit Ctrl-D, and use the arrow keys all the way over to the right where the "corrupt frame count" and "frame corruption rate" are listed (make sure not to move your mouse over the Windows Media Center screen, or the debug pages will disappear).
Once on the frame corruption section, you can then arrow left and right quickly to have it update the info. You will see the frame corruption count increase whenever the glitching occurs in the picture.
Based on all of the above, I don't think this is necessarily a Microsoft problem here, unless there's something intrinsic to how Media Center is programmed, going back to 2009, making it perform crappy with relatively lower end chips like the HD 4600. The HD 4600 really can't be that bad, can it?
I'm curious if there has been any updates? I have been able to temporarily work around the issue by installing an AMD 6450 GPU card, but having an additional card in the HTPC set up is not ideal for air flow. I am hoping to get back to using the on board graphics ASAP.
I'm also curious if there have been any updates. I'm not sure if you read through my in-depth post above or not. but please pass it along to whomever is the expert contact who needs to debug the issue.
FYI, my situation, unlike Mikesterr's, does not allow for a discrete graphics card upgrade, as my system is a mini desktop, so I am, unfortunately stuck with this bug only allowing me to watch a very small number of HD channels on this brand new system without stutter, until this gets fixed.
FYI, I'm using an Avertv Hybrid Volar Max USB TV Tuner (the Kit for Windows, for Windows Media Center) if you need a specific model of tuner to test. Based on this thread, it would be too interesting of a coincidence if we were all using the same tuner. I doubt the cause is the tuner, as I can use this tuner on these problem channels without issue on other machines.
Currently, btw, I'm watching an NBC HD stream, which has 6 channels of audio, and am not dropping frames with it, so the issue may NOT have to do directly with having more than 2 audio channels on a particular stream, but, instead, something more nuanced. Other HD channels are, of course, still experiencing major stutter. The cause might have something to do with the overall bitrate coming in, but so far I've seen no particular pattern to support this idea, based on the 411 debug info
Hello, had anyone from intel looked into this yet? I know there is a new driver out and I have tried it, but the frame rate/flicker issue persists. I built my home theater pc for playing back media, and functioning as a dvr, so an Intel cpu with integrated video was a no brainer. Sadly the flickering makes certain channels very annoying to watch. Specs of my build: Core i5-4570 3.2 ghz/Intel HD Graphics 4600 and 8 gb ram. Motherboard is an MSI B85M-G43. Computer is running Win 8.1 64 and Windows Media Center. It seems that the adaptive contrast function is what causes this flicker, but there is no way to disable it in the Intel control panel. Can anyone please help? Thanks.
I found the setting here: Intel HD Graphics Control Panel > Video > Image Enhancement (Hidden drop down menu, not the Select Profile drop down) > Advanced > Select Disable under Contrast Enhancement, then apply. This seems to have resolved the issue. I will report back if the flickering persists. Thank you.
There are at least two different issues being discussed here. I'd read about the issue Prez808 is describing elsewhere. My understanding is that that can be fixed by disabling Contrast Enhancement or some sort of auto luma setting. That's not what I'm running into. Here's a screen capture of the issue I'm seeing (along with the corrupt frames reported in the debug menu):
I get that black corruption appear from the bottom every second or two, along with other MPEG-2 pixelation artifacts and audio stuttering. Like I've said before, this only happens on certain channels. To be sure, when plugging in the same tuner and testing the same channels on a different computer, I don't have this problem. I just tested this same channel when the tuner is plugged into my laptop, and it displays without any issue.

I've tried this great tutorial quite a numbers of times, methodically adjusting each settings in attempt to understand why and how this works. Alas, the result is either inconsistent or just plain a-no-go, for me.
So, in desperation, I abandoned all hope for interactive subtitle/audio switching capability with MBC/WMC and decided to be diligent in managing my media with a single subtitle.. I am going to stick with LAV filters:
Issue: Internal subtitles won't show up at all for me! xy-VSFilter shows up fine for external subs. I even tried uninstalling xy-VSFilter to make sure I am only dealing with Internals.
LAV splitter appears to work correctly (it creates sub title streams), however, LAV video does not have a build in subtitle renderer. Install xy-vsfilter (NOT xysubfilter which is available on the same site) from here -vsfilter/ . If you have 64 bit windows, you need to install both the 32 and 64 bit so it works in media center. If it is all working, you should see in little green arrow in the system tray.
