OK, here's a question for you:  It seems my CPU and disks are fast 
enough to process real-time capture of video using filters acceptable to 
me, that give good video output for this selected media.

Given those circumstances, is there any advantage to capturing in an 
uncompressed/lossless format and re-encoding after the fact, as compared 
to just directly capturing to mpeg2 from v4l device?  Assuming the 
filters I'm using are the same in either case?
