I have always been interested in Netflix streaming, but I could not get over not being able to adjust the playback speed. That and the movie selection stinks (out of 159 titles in my queue only 40 are available to be streamed). I stilltried streaming for 30 days and really liked some of the original content Netflix had. During that time I did not find anynative way to adjust the playback speed in their html5 player. This really stinks as I am used towatching video with Vlc, YouTube, and MythTV all of which allow for playback speed adjustment up to 2x. It is hard towatch anything at lower speeds anymore. After a bit more searching I finally found a way to change the playback speed inNetflix streaming video.

After much searching I found an Google Chrome extension calledVideo Speed Controller,which allows for the speedup of html5 video streams in the browser. Netflix has an html5 player so this works withNetflix streams. Hooray!! The speedup stream does not have any buffering issues and I've watched many things onwith 2x playback without issue. Unfortunately you can't use this anywhere other than the browser. Come on Netflixplease add playback speed adjust to all of your players on all platforms!!!

Beware that when speeding up video you will need to make sure your video card can handle the higher frame rates.When I stream a video file from local storage with a local program like Vlc at 2x, it is very smooth, without muchjitter or video tearing. When streaming content from Netflix or YouTube or other sites using this browser plugin you are using the browser as the video player, and it might not be as clean of an experience. You might notice some morejitter in the video and some frame tearing on fast moving scenes. This usually happens if your hardware can't keep uprendering the video or if hardware acceleration is not enabled.

My testing for this is being done on Linux with Google Chrome using the accelerated Nvidia Drivers with a GeForceGT 520 a video card from 2011. What I had to do to get rid of the jitter and tearing is turn hardware accelerationon in Chrome. Google seems to be very careful about whether or not they turn on hardware acceleration. They usually don'tturn it on unless they know for sure it will work. Mine was not turned on even though I had a video card that supportedacceleration and the correct drivers. Chromes detection of this might not be the best or Google did not think the drivers for this were stable enough. What is great is you can turn this on anyways and it works great.

To see if your hardware acceleration is already turned on or not type "chrome://gpu" in your Chrome URL bar. If it'sturned off you will likely see lots of red text indicating so. Look for "Video decode" and see if it says "Disabled". If so you will need to turn it on. If it says "Hardware accelerated" then your good and can skip the rest of thisparagraph. To turn on the hardware acceleration in the Chrome URL bar type "chrome://flags". The first setting says"Override software rendering list". Click the "Enable" to turn on the override. Then restart Chrome. Go back to"chrome://gpu" and see if it says "Video decode: Hardware accelerated". If so go try to watch a movie again or a YouTube video and it should be much smoother and likely have less tearing. If you don't have less tearing, go intoyour video driver config and make sure you have Sync to VBlank enabled. Mine is in my Nvidia X server settings managerthen under "OpenGL settings"-> Performance. Check the box "Sync to VBlank".

Normally my Internet Speed with Wi-Fi in my room is about 300-400 megabits/s. Somehow, when I watch Netflix on my TV and I do a speedtest on my phone, the speed drops to 50 megabits/s. When I stop the Netflix Stream, the speed immediately goes up to 300-400 megabits/s. (See screenshots).

Why does that happen? It is impossible, that a Netflix stream takes so much Internet Speed. On the Network Monitoring of Duma OS my Samsung TV is only consuming about 0.20 Megabits/s when the Netflix stream loaded. Yet the Speedtest on my phone shows a speed of 50 megabits/s.

That might be. I know, there are no QoS Settings in the ISP Modem, but who knows. I use the ISP Modem in Bridge Mode to connect to the Netgear Nighthawk XR500. So, you think it has nothing to do with my QoS Settings on Duma OS?

Okay so we can rule that out then, that is good. May have just been a weird fluke. No you don't need to reboot to save any changed settings, they will either change instantly or if there is a save/apply button then press that and it will save.

Below, you will also find a video, where I start a speedtest while streaming Netflix. You can see how the speed drops to around 50 megabits/s. In the middle of the speedtest, I pause the stream and you can see how it immediately goes up to around 220 megabits/s.

Well some Devices are offline, the ones that I don't use. But all the devices I use are connected to the XR, especially my Samsung Smart TV, which I use to watch Netflix. On the Network Monitoring tho, I don't see any devices taking the bandwidth away, even when I watch Netflix.

Well I have one ISP Modem and the Netgear XR500 Router. The ISP Modem is connected via a yellow LAN Cable, which was included in the Netgear Nighthawk Box to a LAN Port of the Netgear Router. The ISP Modem works in Bridge mode, so my internet connection comes from my Netgear XR500 Router.

Correct. I just tested again and the issue is still here. In the network monitoring you can see, that no devices are consuming a lot of bandwidth. My Samsung TV is only consuming 0.5 Mbit/s when I am streaming Netflix on it. Yet, when I do a speedtest while streaming Netflix, the internet speed drops from around 300-400 Mbit/s to 50-100 Mbit/s. The moment I pause the stream, the internet speed goes up again.

Then, I reset the network settings on my TV and tried using it without internet connection. Same issue again, the internet connection dropped, even without connecting the Samsung TV to the internet. As soon as I turned off the TV, the internet connection was good again.

I'm feeling like this may be a coincidence regarding when it drops, as you said, not much bandwidth is being used so no need to it to drop. Could you test direct to the ISP modem/router and see if you see the same behavior?

There is no way I can test this at the moment via LAN, because the ISP Modem is in another room than my TV is. I will be able to use LAN ina few weeks. Plus, I get my internet from the Netgear Router and not from my ISP Modem, since the ISP Modem is in bridge mode.

The modem provides internet to the router so if for some reason the modem or the ISP is limiting the speeds during these brief periods then you'll be able to tell by connecting directly to the modem. If you take it out of bridge mode you could try with its' WiFi instead.

I turned my TV on and I did a Speedtest on my iPhone and on my Laptop at the same time. Both devices were in the same room. The iPhone showed a speed of 40 mbits/s. The laptop showed a speed of 300 mbits/s. Both connected to the 5 Ghz Wi-Fi.

Then, I connected my Laptop to a LAN Port of my ISP Modem. On the iPhone I had around 150 megabits/s with Wi-Fi and on the Laptop connected via LAN I had 330 megabits/s. Same result when I connect my Laptop on a LAN Port of the Netgear Router.

The most believable numbers I've found are 1.5Mbps for SD, 3Mbps for DVD quality, 5Mbps for HD quality and 8+ for 1080 on PS3. I don't see Netflix offering official numbers, but playing with Speedtest.net and testing by adding bandwidth eaters like VPN connections until I saw the quality degrade.

While I couldn't find any hard numbers on Netflix's site, it seems the consensus is that as long as you have a decent DSL connection 1.5 Mbs, you should be able to stream successfully (there might be a decent amount of buffering though).Source

I do not personally have Netflix, but my aunt does (the standard definition version through a Wii) and she has no problem watching movies with connection speed that hovers between 700 Kbps and 900 Kbps (tested at Speakeasy.net). I was actually surprised that video playback didn't lag with speeds that low, but there it is.

We have a 1.5/10 Mb connection and see neflix eat as much bandwith as it can get. Not uncommon for it to be using 9mb on HD programs over our xbox 360. However if there is anyother machines online it will kick back to less and change the quality of the stream...

This is Neil Hunt, Chief Product Officer, to tell our members in Canada that starting today, watching movies and TV shows streaming from Netflix will use 2/3 less data on average, with minimal impact to video quality.

I ran the Activity Monitor app on my MacBook Pro while simultaneously streaming Netflix on 4 devices on my home wifi (my MacBook Pro, an iPhone 5, an iPhone 4 and a smart TV upstairs). The total data rate never got higher than 709 kbps (less than 1 Mbps) and on average it stayed around 200-300 kbps. All devices were streaming flawlessly. I even called Comcast on my VOIP phone and the bandwidth usage stayed the same.
