So I am trying to convert some PBS programs from the HD-3000 recorded NUVs to DVD MPEG2 format. I installed nuvexport to make my life a little easier, and it works on converting my recordings to MPEG4, which I believe is using transcode and not ffmpeg. The convert to DVD however is a problem. It looks like FFMPEG is not working correctly because the resulting file is corrupted in that there is a color frame sync problem (for lack of a better term). It hard to describe it, so check out this sample :

Suggestions?
MythTV 0.17 ffmpeg is version 0.4.9pre1, build 4732

Not sure what settings you are using to convert, but there are a couple things that you need to be aware of when encoding for DVD's ]
1) there are bit-rate limitations (I can't remember off the top of my head, but somewhere in the neighborhood of 10k MAX including audio) which can *never* be exceeded. 2) there are also resolution requirements.
Since the HD-3000 already captures MPEG2 streams, you really are mainly concerned with resizing, and resampling to a lower bit-rate.
O.K.
I downloaded the file, and tcprobe -i tells me:
[EMAIL PROTECTED] completed]$ tcprobe -i sample.mpg
[tcprobe] MPEG program stream (PS)
[tcprobe] summary for sample.mpg, (*) = not default, 0 = not detected
import frame size: -g 720x480 [720x576] (*)
aspect ratio: 1:1
frame rate: -f 23.976 [25.000] frc=1 (*)
PTS=0.5000, frame_time=41 ms, bitrate=104857 kbps
audio track: -a 0 [0] -e 48000,16,2 [48000,16,2] -n 0x50 [0x2000] (*)
PTS=0.5000, bitrate=384 kbps
-D 0 --av_fine_ms 0 (frames & ms) [0] [0]This tells me your bitrate is through the roof. You probably want to pull your video bitrate down to the 8k range.
