to be honest... video performance (right now) sucks very hard. i don't need HD-playback because the screen resolution isn't even HD (800 * 480) as mentioned few times before. but what's driving me crazy is the fact that i have got many .avi and .x264/.h264 videos created as a compromise between resolution, bitrate and of course filesize. so mostly they have around 700 * 350 px and between 1200 and 2000 kbps on video-side and around 300 kpbs 5.1 ac3 on audio-side.
