Hi,
I encountered the same problem. Videofiles would show in my fullsized-dvd pubs, but mp3files (inserted as videos with a scrollbar -about a hundred or so

) would only play once. After playing that one file, selecting and playing another soundfile would result in the moving pointer flashing from left to right without playing any sound.
It did not happen on all machines, only on rather new computers. The cause must have been an update in Windows xp and Vista, because the pubs ran without a problem earlier on the same machines. The update must have changed the mediaplayer or some codecs.
Installing ffdshow repaired the problem however. It caused me some bad nights and days before I found a solution.
regards,

Ps. Installing K-lite would cause the soundfiles to be played correctly, but froze the videofiles
