While the ATIs are nice, my personal favorite for this type of work
is
the Matrox G450Max. Awesome dual-head capability and S-Video inputs.
If you have the BETA player, you can setup an hour or so to do this
at my house. I'm in Fenton.
Here's your recording options:
20 minutes = 20 x 60 seconds = 1200 seconds.
Max recording via my PC-VCR software (MJPEG), which can then
be converted to smaller MPEGs or streaming media.

As you can see the raw file size of a *tiny* image with no
audio is >200 MB.
It should be obvious to everyone why video on the web has had limited
success, and is directly dependent upon fat pipes (broadband) to
the curb - be that cable, DSL, satellite, or fiber.
I tried compressing a five minute video of my son's ultrasound
for the web, and it was barely sufferable at that smallest size,
no sound, and higher compression - something only a grandparent would
wait and wait and wait and wait.... to see. :) It was a little over
2MB.
I have a Jaz (1GB) cartridge, so if you bring your own cartridge, we
can
record it onto that. Or I can find a temporary home on the web,
upload it,
and you can download from there. That way you don't have to sit
through
yanking it from my DSL upstream.
