glitches on some mpegs

[compunett]

I'm running a macosx 10.4.3, with VLC 0.8.4

When I play some MPEG2videos, I actually expérience glitches in the video and in the sound. According to the information VLC reports, there is 3 streams inside this file

1 - mpgv : the video of course
2 - lpcm : the PCM stream actually it doesn't output anything at all (normal the support of those stream iscausing problems under osx)
3 - mpga : and this stream, which does play

However in the file gltches appears, i see wrong macroblocks on the video, the audio sometime becomes sloppy (videos is also sloppy at the same time).

By the way other files with only mpgv and mpga expérience the same problems on VLC OSX.
EDIT: I tried a VOB file with LPCM the file plays, but again gliches appears on the video and the audio get impacted as glitches appears there too.

On the VLC Win32, the information on the file didn't mention any LPCM, and the file plays just well.

2nd EDIT:
It seems that 0.8.2 play correctly the video for these files, they are captures from dvb

Here is the message logs

It seems there is some erros in my files, but vlc on MacOSX couldn't handle them, i didn't remember any problems with vlc 0.8.2 but at that time it was under OSX 10.3.
