Yep, the compression of moving images causes the lower frame rate and increased
bandwidth. Because of this, IMHO, full quality video will require the
compression to be done on the capture board. for internet use, we probably
would want only MPEG 1 quality, but leased/wider bandwidth networks will use
MPEG 2. unfortunately, MPEG 2 capture boards are very expensive ($4-5K).
