Thanks for posting benchmarks. So right now we can suppose that MPlayer seems to play 30 fps video on N800 roughly the same as it plays 24 fps video on 770 (http://maemo.org/pipermail/maemo-dev...er/006646.html). That is if video does not need to be scaled (if scaling was needed, 770 performance would be much worse in video output). These results corelate with cpu clock frequency increase (24 fps vs. 30 fps and 250MHz vs. 330MHz).

Well, playback of nonconverted video even on N800 is still a challenge. Optimizations for ARMv6 SIMD instructions can help to make it faster. Also N800 has a specialized video accelerator (IVA), if it could be used, maybe the results would be a lot better.

By the way, it is possible to enable grayscale mode if cpu performance is not fast enough to play some movies, it works a bit faster (-lavdopts gray). But it is much less fun to watch for sure.
