Maybe you already know this but here goes anyway. If you "allow" a video to download, in all its choppiness, when it does finish, you can replay it and it will playback the way it should. It might take some time and you may need a download manager but it will work. Just downloaded a 4 minute video on my sisters dialup, it took some time, but afterwords, it played back just fine.
Only a suggestion,
You asked me a loaded question, when I once again tried to watch a video,[Make your own podcast] "How do you like our Cnet Video's?"
The answer is I don't. I live in the country and have no access to anything but dial-up. Every time I attempt to watch one of your videos they are buffered so badly I want to bang my head on the wall. I have made repeated attempts to take your online courses but because I have to watch impossible to watch videos I have given up and no longer bother. Being on a phone line you make me feel like a second class citizen. Sincerely "Catman" Donald M Peterkin
