Video wants to catch the sound to keep in sycnro

[kimiraikkonen]

Specs: P4 2400 MHZ, 768 MB DDR, C-Media CMI8738 on-board chip, Geforce4 MX440 with forceware 84.21. All settings are normal and default, no heavy start-up apps.

Sometimes, if i run a MPEG2 movie, at the beginning of file, the video runs slower, but the sound goes smoothly,normal. After being out of sync because of the video is slower than sound, the video plays to much fast and tries to catch sound to keep video in syncro. I have no frame drop.

I use "internal renderer overlay". (Mainconcept 1.0.0.78 decoder with BSPlayer 1.41)

Why? My computer and its resources is too strong to play, even i was playing without problems before.)

Any help will be appricated.

Thanks...
