so the variance in quality of recording between a vhs tape & DSS/Cable

colors on playback (greens, fuzz, etc)...


If you're trying to compress crappy quality video, you'd benefit if you clean it up with a filter first (else you're just wasting bits encoding noise).VirtualDub would be the obvious tool to do it.

also, maybe becuase it was
recorded by a unsteady hand using a one of those vhs cam
recorders(?)...as such, instead of people just moving, you get the whole
image canvas also moving becuase of the 'unsteady  hand' when recording.

Interesting point! I guess if the picture is moving around more than desired then maybe you're killing CPU cycles by having to use a wider motion search in the MPEG compression to achieve the same result. It'd be interesting to take a "shaky" video, software image stabilize it, and do an MPEG compression time/size comparison.
