just a heads up for you guys that DVICO have just released their 3.0beta2 drivers.
Interestingly, DVICO state on their web that the new drivers now have a native MCE2005 HDTV decoder that has the best compatibility and performance among HDTV decoders, and works specifically with MyTV! Ooohlala
Just a warning though, they're not small @ 75MB! (or 45MB for individual drivers)
