Slow playback on fullscreen (not resolved yet)

[gonza87]

I used the search engine, and i didn't find my problem solved yet.

I have bs.player 2.40 build 997, running on a
Intel Celeron 2.66 Mhz + 512Mb ram + video card GeForce Mx 400 64mb Monitor: Samsung T220N, resolution 1680 x 1050 60Hz.

The problem is: at fullscreen mode, any movie (.Avi and .mpg, DVDRip quality), is played slowly. Instead of that, with other video players like VLC, at fullscreen mode too, any movie is played well.

I have FFDSHOW filters, but Post-processing and all other options are unmarked.

Any ideas of where's the trouble?

Thanks and sory about my bad english.
