So... I got it today.. installation wasn't an issue, in fact, I used a USB stick and it worked just fine.
Mostly everything is working, but for the life of me, I cannot get xvids to work (with Dolby sound).. xvid with AAC works fine, but DD won't work. I have it going straight thru HDMI. I tried SAF 4 and 5... and just FFdshow. It seems to be pushing SPDIF, while the AAC xvids pushes to PCM.
What are your codec settings set to?
What OS are you running? I'm curious if it can deal with W7 (for MP2).
