Importing video on Powermac 7600 G3

After agonizing over this for a long time myself, I thought it was time to see if I could get some help from some fellow classic Mac gurus. Here's the problem, I am trying to digitize short video clips from my VCR onto my Powermac 7600. Hardware specs: 10Gb SCSI hard drive, 256Mb of RAM, and 333MHz G3 upgrade card. I've tried using Apple Video Player and the video quality is WAAAAY too choppy to be usable. I got BTV Pro installed, and while it does work better, its still not very smooth. I've tried different combinations of compression and then turning compression off entirely. I'm not trying for anymore than a few min of video, and the window size is small (320x???) The Mac is running 9.1 with QuickTime 6.0.3 installed. Anyone know of a way I can get better quality video outta this thing? Here is a link to a shot video I made so you can see what I'm talking about. I just don't know why its dropping frames all the time.
