Re: Performance of mplayer playing back WMV is miserable
 

Wrong - it is a hardware limitation - the DSP won't work on bigger frequency.

Don't mess IVA (part of the processor, 2D) with the PowerVR OpenGL ES accelerator (part of the processor, 3D, external vendor) - I'm sure Nokia will use IVA if they could on this big screen, while the 3D acceleration needs different driver and probably licensing fees.

MPlayer is still not fully optimized for ARM11 yet and there are still some optimizations possible. I'm not saying that it will be able to decode any "downloaded" AVI file, but video playback support can definitely become better than it is now.

As for WMV video files, most likely slow WMA audio decoding is at fault (one can run mplayer with -benchmark option to see what is taking most of the time). That is unless WMV9 is duscussed in this thread, which is much more heavy and hard to decode even for desktop PCs.

Actually, no, he's correct, stepping down to 330MHz is a software issue, easily solved by a new kernel. The argument you could make is that the DSP couldn't handle some mp3 decoding stepped down when the ARM core is at 400MHz, but I haven't seen any information as to what the DSP can and can't handle at certain clock speeds. Either way, best not to assume Serge doesn't know what he's talking about. ;)

I realize you can't have full CPU speed and full DSP speed at the same time.

I've read (and my experience agrees) that OS2008 prioritizes DSP speed over CPU speed. That's a software limitation.
