How to use downthemall in video downloadhelper?

Hi, I'd like to know how to use downloadthemall in video downloadhelper?

The download speed of VDH is too slow which is about 1Mbps that I cannot bear it!

I used to read a port about VDH now is support DTA, but I do not how to make it.

I would be grateful if you help me.

Thanks a lot.

I can't help you with Down Them All but I'm curious about how you came to your 1Mbps measurement.  Where are you measuring this number?  Is this slow speed something you observe on all sites?  If you don't use VDH for a download, what speed do you get?  In my experience, VDH uses whatever bandwidth there is to be used.  Some sites allow more, some less.  On the Metropolitan Opera web site, captions download rather slowly, like in the 100,000-200,000 bytes per second range, which is actually not noticeable since captions are usually only in the 200K size range so even on a slow connection, they take only a few seconds.  The audio streams come in around 4 million bytes per second.  The video streams come in somewhere around 8.5 million bytes per second.  YouTube is reprehensible in the way they throttle downloads.  When I first launch a YouTube download, it uses about 1 million bytes per second.  But if you watch closely, if the download is large enough, the speed gradually drops until you're getting about 350,000 bytes per second.  That's no better than I ever got before I switched ISPs & got an actual high speed connection.  So download speed is as much a function of the serving web site as it is a function of the downloading software you're using.  I'd say the speed of the server is way more of a controlling influence than your downloading software.  If your bandwidth is as slow as you say, no change in downloading software is going to improve that.

I take my measurements of download speed from the Windows Resource Monitor, a tool built into the operating system.  They most sensibly use the speed unit bytes per second.  ISPs like to use smoke & mirrors to tell you about their bandwidth offerings.  They like to quote things in Mbps.  But first of all, I take issue with the M.  M is supposed to mean meg.  To understand meg, step back to K.  1K=1,024.  1,024 is the number 2 multiplied by itself 10 times, 2 raised to the tenth power, 2**10.  1K is not 1 thousand.  1K is not 1,000.  It's 1,024.  1M=1Kx1K=1,024x1,024=1,048,576.  1M is not 1 million.  1M is not 1,000,000.  1M is a larger number, 1,048,576.  But when ISPs tell you about their bandwidth & they talk about M, they mean 1,000,000 which is NOT 1M.  In addition, the bps part is actually bits per second.  When was the last time your operating system told you the size of a file in bits?  I thought so.  Never.  Computers & people think in bytes.  ISPs are preying on the ignorance of the masses when they tell you your bandwidth is 1Mbps.  Since 1 byte is made up of 8 bits, a speed they quote as 1Mbps is actually only 125,000 bytes per second.  Divide by 8.  I do agree with you that 125,000 bytes per second would be an excruciatingly slow connection.  But I don't agree with you that this is due to VDH.  I ask again, how are you taking your measurements?

I like to take the extra few characters to express bandwidth usage as bytes per second.  This avoids the whole issue of whether M means the real M or the phony 1,000,000.  It also makes clear that I am talking about bytes, units we all are used to dealing with, not bits.  I recently changed ISPs because my old ISP was taking years to install fiber optics where I live.  My usual bandwidth used to top out around 550,000 bytes per second.  That ISP called that 5Mbps.  Notice the smoke & mirrors.  My new ISP was able to offer me a service they categorize as 400Mbps.  In practice, using certain speed test web sites you can find all over the web, my speeds are actually measured as being upwards of 460Mbps.  But let's accept their 400Mbps for the moment.  First, it's not M, not 1,048,576.  It's 1 million.  Second, it's bits, not bytes.  So correcting this misleading number, my bandwidth is actually 50,000,000 bytes per second.  Still, not too shabby, but not 400 million anything.  In any case, in the month or so that I've had this fancy new service, the highest I have ever seen Resource Monitor reporting is in the 18,000,000 to 20,000,000 bytes per second range.  Comparing this to what I used to have just makes me laugh.  An opera used to take me 2.5 to 3 hours to download.  Now, even with the Met not coming close to using up all my bandwidth, it takes roughly 10-12 minutes.  3 hours compared to 10 minutes.  That always makes me smile.  But it points out that whatever your ISP tells you is their top bandwidth, my experience is that no web site lets you download at that speed.  Everybody throttles their download speed.  That makes some sense since a web site needs to preserve some capacity so everybody who wants to download can get some reasonable share of their capacity.  9,000,000 bytes per second may be not even 20% of what my connection could handle, but it's still plenty fast.

So it comes back to my original question.  How are you measuring your bandwidth usage?
