Hi Greg,

I must say that my experience is a bit different. I use a via M10000,
which has a slightly slower CPU and I don't see any problem with OSD
fade when watching live tv (I have XvMC turned on BTW). Perhaps the
problem is in the driver, rather than with Myth. AFAIK, the M10000
uses the unichrome video chipset, but the SP13000 uses the newer
Unichrome Pro chipset for graphics. Perhap the support for this
chipset is not as stable in the driver, which might explain the
difference ?
