I've been using avidemux in the past to recrunch pvr-250 recorded
streams onto DVD. Not too much difficulty, and it appears that I always
get a 66ms difference between audio and video. With this tape transfer,
however, it appears that the A/V sync amount changes as the tape recording
goes on. Maybe because the pvr-250 had to do weird things because the VCR
that was playing the recording did odd things at the cut?
Why not record directly into a dvd mpeg using your pvr 250?
I've been using gopchop to cut up mpeg streams. Downside is that you can
only cut every 12 frames (I think), but it doesn't do any recoding!
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.
