hmmm,
1) you might try to download the samples listed on the betaplayer site:
http://betaplayer.corecodec.org/
2) if you are still having issues, you might try to let picard (the programmer) know. He hangs out a lot on this forum:
http://www.corecodec.com/modules.php...viewforum&f=24
3) you might also try to encode a sample of your own (DIVX or XVID)
good luck,
