Problem with video playback

[Guest Lestat.me]

Hi, I've a Toshiba TG01. I've a problem with video playback using either Coreplayer or TCPMP. Video playback is a little slow with all the videos I tried. The results of the benchmark are really positive (+300% with a Mpeg4 video, resolution 592x320) but there is some stuttering in the playback. When I try with Raw FrameBuffer video mode the playback is smoother (benchmark result is worse) but there is too much tearing in the video, like in a PC videogame with vsync off, same with GDI video mode.

Is there someone with the same problem? Is there something I can do to remove this problem?

Sorry for my english, I'm italian.
