Fast (tetsuized?) Kernel For Sharp Rom, Does it help mplayer play wmv files better? Options

My 6000 is a favorite device, except for one thing. Video playback of wmv files! They are slow motion, and choppy. I wonder if installing the fast kernel as described here would help. I also have an NEC MobilePro 900C (with cmonex rom) that has the same processor and a screen that is ... how should I put it? AWFUL! Yet it will play these wmv files just fine. It has no video acceleration (that I know of). It kills me that my Z (with it's gorgeous screen) can't do this too!

Has anyone used the instructions linked to above? Are these instructions fairly dummy-proof? Will this kernel help with mplayer? And is this kernel 100% compatible with Sharp ROM and ipks I already have?

I don't think Toshiba *ever* released the full programming manual* for the tc-6393 "companion chip", which would cover video acceleration. Many of us have tried to use their contacts to get a copy. Sharp never released source code to their kernel module. One guy managed to make a few inroads into getting some of the acceleration going but for some reason he stopped, I think he did it purely by hard work and random poking!

There are various theories why, the only one that vaguely makes sense is that the 6393 is also the SD controller and since that was proprietary, Toshiba probably didn't feel able to release any information.

The same chip was also used in another PDA, an ipaq or something, and the guys working on that also floundered.

So, if you know anyone really really technical at Toshiba, do ask them if they can provide the programmers manual and then we'll get video acceleration!
