I updated my athlon with latest 4-in-one via drivers which allowed me to update the g200-tv with drivers to allow yuy2.
Now using picvideo ( jpg.com )

Capture at 480X480 with picvideo and virtual dub, and then run thru lsx-mpeg encoder with a 3.5 hour per hour of video for conversion to mpeg-2 at 2200 CBR interlated video.

Very good results.
