Panasonic Viera .avi trouble

[boneslammer]

I've ran into a problem with a whole bunch of .avi files.
The issue is, that after a few seconds of playing it starts to pixelate, skip ahead, and some weird stop and go. After 10-30 seconds it comes to a complete stop.

After checking a lot of different avi's from different sources i have narrowed it down to those that use mp3 as audio codec. never had this problem with files using ATSC A/52 / AC-3.

But on the other hand, 50% of those using mp3 work perfektly. So i'm not sure thats the problem. After looking at the properties of the files, the audio codec is the only difference i could find.


Any suggestions?
