Had to switch to Spdif because my entire surround system was moved away from the tv to the other side of the room while my nas and htpc are now standing next to my switch in the cellar. Previously my htpc was right next to my Yamaha Surround system so I could just connect it using HDMI passthrough.
chewitt Never heared about this bevor, Can hardly believe that such a huge issue still exists. I am currently checking my exact TV model and will give your idea a shot. However, I did some reading on the nvidia forums and it appears like it should be the other way around, with video stutters instead of audio dropouts. Can you recommend me some articles to read up more on this issue? Sounds highly interesting and very important should I decide to build/buy a new htpc in the future.
EDIT: Wait, I think I understand where the problem is now. My video uses the graphics card onboard clock while my onboard spdif audio output uses the mobos/CPUs clock, and they are not always necessarily in perfect sync. After a while this results in the audio pausing for a second so that the video can catch up to it. So I can now either try to solve this issue using software, get a new graphics card with a spdif audio out (has anyone ever seen such a card?) or use a splitter after my current graphic cards hdmi out to split the signal into audio and video.

OK, so after nearly disassembling my TV I figured out that its a Philips 46pfl9704h. Problem now is that there I can't seem to find any data on it. Is there a databse or something where I can look this up?
