If you still have problems, E-mail me . My band has a cool video. Sure, you betcha. It won't sound or look real good though. At the 56 kilobits per second rate that most modems use, it's amazing you can even get halfway decent sounding audio to play in realtime.
Video is even worse.
Here is a speech I gave at Wenatchee Valley College in RealVideo format. It was actually pretty bad right off the VCR tape, so your video may look and sound slightly better. Stereo Realaudio files sound like total crap because it is simply too much info to send over a 56k modem. If you think about it, a modem can only send or receive at 56 kilobits per second, whereas a CD is playing at about 1378 kilobits per second. If you want good sound quality, download the MP3 file.
