One thing that really has disappointed me in my Nokia N800 and other handle is that they can't handle high resolution videos. Even 640x480 high-bitrate video can't be played back without shuttering or dropping frames. Of course playing back unconverted 1920x1080,1280x720, or even smaller video is unwatchable.

What I have been looking for is Handheld device that can play back my high-resolution, bit-rate anime video files without any problems. Most of these files are encoded in x264 (not same as H264 codec). I am trying find handheld has good resolution (800x480), like N800.

Any suggestion on handhelds that can actually handle high-resolution/bitrate videos? Probably a handheld with hardware decoding for videos (like ATI Imegeon + TCMCP) should be able to handle it. But I haven't really heard any verified information about this yet.
