Default Jerky playback

Hi everyone !

I've decided to register to let you know of what I assume must be a bug. I'm using latest version of BSPlayer 1.00.807. See all details of my configuration and movie at the end of this post.

Problem is : while playing a 2CD DivX movie with BSPlayer, in some parts of the movie (always the same), playback gets jerky (sound and picture) and video tends to freeze and get back to normal later on without my intervening. It only lasts 15 to 30 seconds and curiously sometimes the jerking does not occur at all. I've tried all sorts of changes with the settings of BSPlayer, used DivX decoder instead of FFDShow. The problem remains.

However if I copy the movie file on my CD hard drive, it plays perfectly. Same if I make a disc image and mount it in a virtual CD drive. You might think it has something to do with my CD recorder /DVD drives but I don't think so (DMA for all drives is on of course) as I've tried playing the same movie in the same drives using Gabest Media Player Classic and the jerking never occurs. MPC apparently uses the same decoder and filters as BSPlayer to play that movie.
Hope the developers manage to fix that soon as BSPlayer is such a good player it'd break my heart to have to use another player.
In the meantime, if I forgot to provide important info to help sort that bug, I'd be glad to post it ASAP.

Keep up the good work !
