The few known limitations of this player are:

* only < 352x288 resolutions and only 16x multiple
* jerky playback in full screen
* no B-frames

No problems with high bitrate/framerate, no CPU overloading with mpeg4. This is the reason why I hope Serge will use DSP for video too.
Well looks like you still don't get it :-) The thing is that DSP is another CPU. Default player does not use main ARM CPU for decoding (both video and audio) at all, but uses only DSP. That's why main CPU is below 25% and playback is jerky. The DSP in fact is constantly at 100% when playing most videos and is screaming for help :-) You don't see DSP utilization in load plugin or top command or whatever. You need to watch /sys/devices/platform/dsp/loadinfo to see it.
