Hello. When I try to play a recorded television video on VLC, the sound doesn't come out right. It is all choppy and garbled so I cannot understand anything anyone is saying. BUT, when I use Windows Media player or the GOM Player, the sound comes out perfectly fine. Winamp also doesn't play the file correctly either. The format of the file is *.mpg. Does anyone know why VLC doesn't work right with recorded videos in mpg? Are the codecs different compared to Windows Media player? Help please and Thank you.

VLC uses its own libraries to decode media files, it is not a Direct Show player using Windows codecs.

While playing the problem video press ctrl i and go to advanced information, post that info here.

if you demux the audio from mpg, does VLC play it correctly?

What is "demux" mean? and how do i demux from the mpg?

demux is short for de-multiplex which means separating audio and video from original mediafile. You can do that with many different tools, like TMPGenc and its File -> MPEG tools... and de-multiplex tab (audio should be .mp2 after that).

I'm having similar problems with MP2 audio in MPEG files. The audio pops, clicks and chops or completely cuts out regularly when playing the MPEG. After demuxing the audio with DGIndex, VLC can play the MP2 audio on it's own perfectly fine.

(Vista SP1, VLC 0.8.6e)

Could you give a link to sample file?

I'll see whether I can cut a section from one of these files and upload it somewhere.

Sample to be found here (1min, ~9MiB): http://users.telenet.be/marcswinnen/mp2sample.mpg

The files play fine in VirtualDub and Windows Media Player too, if that matters.

File works just fine with my VLC. TSremuxer doesn't like it because the file has padding stream (many other tools also hate padding stream). So I remuxed with TMPGenc. See if it works any better.

[EDIT]
Just for the heck of it, I've done a complete uninstall/clean/reinstall of VLC (uninstall, delete all folders/..., clean registry), and it appears to have solved the problem. Something must've gotten garbled with an update somewhere (even though I select the clear preferences/cache and all). I guess I'll need to do a thorough clean every time for VLC.
Another thing I've noticed: The "Minimize number of threads" setting introduces repeatable glitching in these MPEG files.
