That's what I'm trying to do now. I played with GOPCHOP awhile
back, but at the point it broke the MPEG stream around the cut. Avidemux
didn't do that, so I started with that. In the past, I was going for the
best possible quality/size. My "archival" of TV shows is typically done
at 352x480 on the DVD. The PVR-250 recordings at that low of a resolution
is pretty crappy. I record at a higher resolution (640x480) and higher
bitrate (4-5Mbps), and then downsample in both size and resolution with
2-pass encoding. Much better quality per filesize.
