We will need some other chipset users to test this. My results were NOT 
good using SVN 19110 + patch on an Intel system.

I have an Intel 945GM chipset in my mythbox. I'm using the latest xf85 
Intel Version 2.5.1 driver.  But I picked up an Nvidia 8400GS card to 
take advantage of this. But before I put in, I tried the 'upgrade',...
Oooops. Same hardware and setup as SVN trunk 18408 would NOT play either 
SD or HD (I was using High Quality). Some messing got analog SD to play, 
using XvMC (on Intel remember) but the system was NOT happy, and there 
was no OSD. Anything digital resulted in an instant seg fault. And 
nothing useful in the log.

I re-downloaded SVN 19110 (forgetting that I could reverse the patch), 
but it exhibited the same effect...and it was now looking for 
/dev/nvidia0, and seg-faulting when it was not found...

I eventually reverted to 18408. (Still with a funny problem, too.. see 
other thread).

So, have there been 'bad' changes to trunk since 18408 which kill Intel, 
or did I miss something when I re-installed....(yes, it turns out I 
'make distclean' more often than I clean my teeth...)
Anyone else out there, using OTHER chipsets, have any test results from 
using the vdpau enabled code?
