Hmm, Its difficult to say where the actual issue is, suffice to say the video playback is not yet heavily optimised (for example a fragment shader could potentially be used to process YUV data and speed things up). I've only really experimented up to 1024x768 on an intel chipset and so far pretty fine for me. What could be happening is at high resolution the video texture is split into multiples (as a single texture not big enough) and this combined with memory bandwidth is causing issues. I will attempt to investigate further, sorry I cant give much more help atm. -- Matthew -- To unsubscribe send a mail to [EMAIL PROTECTED]
