[mythtv-users] Partly OT: Converting HD content in MPEG2-TS to DVD compliant MPEG2

[casey dunn]

Thanks.  That's a hell of a lot better than what I was coming up with but,
I've still got a few bugs...

When I play the file back in VLC it reports two audio streams the first is
silent the second appears to be the #2 audio stream from the original file,
ffmpeg only show's the one audio stream and totem-gstreamer has no audio at
all.
