[MPlayer-users] Audio out of sync

[Michael Lindner]

I'm trying to backup tivo video to DVD. I have a utility that extracts a 
.mpg file from the tivo file. The resulting .mpg file plays perfectly 
with mplayer.

However, when converting to DVD, the result has audio that starts out in 
sync, but as time progresses gradually gets out of sync with the video. 
I am using the script encode2mpeg to make the dvd, but the result is the 
same no matter what tools I've tried. At any rate, encode2mpeg demuxes 
the audio and video using the command

mplayer XXX.mpg -noframedrop -v -osdlevel 0 -vo yuv4mpeg:file=/dev/fd/4 
-ao pcm:waveheader:fast:file=%10%XXX.wav

so I'm asking my question in this forum. It seems that the original mpg 
file has *mostly* frames at 29.970fps. However, a few of the frames are 
not, as shown below. I'm told this is the reason for the sync slipping:

A: 189.7 V: 189.2 A-V:  0.476 ct:  0.284 5642/5624  2% 43%  0.3% 5073 0 

demux_mpg: 24000/1001fps progressive NTSC content detected, switching 
framerate.
A: 190.0 V: 189.5 A-V:  0.550 ct:  0.303 5650/5631  2% 43%  0.3% 5079 0 

demux_mpg: 30000/1001fps NTSC content detected, switching framerate.
Warning! FPS changed 23.976 -> 29.970  (-5.994005) [4]  3%  0.3% 5080 0

I was wondering if there's a way to fix this so the streams will be in 
sync. There are quite a few Windows programs that do this, but they are 
Windows programs and I am running Linux. I figure mplayer does just 
about everything, there must be an option that can do it that I'm missing...

Thanks in advance for any help.
