XVid - No Video & Scrambled Audio - Tried many codecs

[LonkNY]

I'm having a problem that I haven't ever seen in the past on my system (I haven't made any recent changes to my system that I can think of - especially any that would cause this issue to occur). The problem is this:

When I drag an AVI (using XVid codec for video & mp3 for audio) into Media Player Classic 6.4.8.9 to play it, I get no video at all (the video window collapses so that I only see the MPC menu & control bar) and the audio is scrambled heavily - it sounds as if I am playing an audio tape while fast forwarding... it is a horrible, ear-piercing noise!!

I have never had problems playing XVid vids in the past - I normally use the XVid codec version XviD-1.2.-127-25022006, but have also tried ffdshow's libavcodec and XVid codecs (ffdshow v2-2-2006), as well as the DivX 6.1 codec and older versions of XVid & ffdshow, all with the same results... so I am assuming this is not a video codec problem.

With regards to audio, I normally use the Fraunhofer l3codecx.ax MP3 codec, but have also tried the ffdshow (including older versions) mp3lib and libmad codecs with the same results. Again, it doesn't seem like an audio codec issue either.

When I drag one of the problem files (always xvid/mp3 avi's) into gspot, it seems to render fine and gspot does not crash as it normally does when there is a codec problem. When I play the file in VLC player, it plays perfectly (but as far as I know, VLC uses its own process for rendering video files and doesn't rely on directshow/vfw). This is not a solution for me, however, since I use directvobsub/vsfilter to display subtitles which I don't think is possible with VLC. Also, I would like to convert these AVI files to MPG/DVD at some point.

Has anyone seen this problem? I have installed and uninstalled, enabled and disabled many codecs trying to get this to work and haven't had any luck. If anyone is familiar with this issue and can reply with some suggestions or solutions, that would be great... thanks!!

Thanks again,
LonkNY

Uh... VLC can and will do subtitles. It has internal rendering engine to do it too. It doesn't need VOBSUB to do it.

Download GraphEdit and show us the graph when you load that AVI file in question. Perhaps we can figure out what's it doing.

I think I figured out the cause of the problem... I tried playing the files in MPC v6.4.8.7 and they render perfectly.

Do you know what changed between this version and the newest (I also tried the latest v6.4.9.0 and had the same problems) that would cause this problem? I will try looking at the changelog but will probably not recognize what I need. Thanks again.
