hi there,
I have a Denon 3300 as well. I can't speak for HTPC output, but my pioneer dvd player can pass 24/96 to the receiver no problem. I have the denon set on 'Auto' for the digital connection and when it detects the 24/96 signal it will lock into 'Direct96k' mode (thats what will be displayed on the denon's display. With 24/96 source material you are forced into direct96k mode, you can't switch to 5ch stereo or anything like that.
