You have to enable both XVMC and XVMC VLD to enable the unichrome mpeg 
decoder.

What you are seeing is probably Xv out with hue setting that is off.

I must say I also upgraded my kernel, got all the unichrome stuff 
working even with the limited colour OSD theme.
But after goin trough all that I tried using my epia-M10k without the 
hardware acceleration and it now works without any stuttering (even with 
deinterlacing on) and full color OSD. It never used to work with my 
previous install with the 2.4.26 kernel. So I'm happy now *not* unsing 
unichrome hardwre accel. It must have something to do with better 
preformance with either the new kernel or the new unichrome via video 
drivers.
