After getting a US 360 HD DVD drive from the guy in red and getting it working on my HTPC I am hearing the occasional audio glitch. Whilst watching King Kong I had apoximatly 20 occurances. It's hard to describe but basically the Audio will cut out for a fraction of a second and then continue. I would call it stuttering but that would emply its regular/repeated cut outs. It doesnt seem to effect the picture and I dont think it's because my system is struggling. I have an HDA X-Plosion card connected to my AMP via Toslink. Using PowerDVD ultra. In addition, after reading the "360 HD - poor audio" thread am I connecting my HTPC to my amp via the wrong connection? Will I get better quality using COAX or even using the PCs DAC and outputting via analogue? I'm running a 5.1 system BTW. (I have a HDMI GFX card but it takes its audio stream from a SPDIF header, so that would be no better even if I did have a HDMI amp/TV). With the new formats (Dolby Digital Plus, Dolby TrueHD and DTS HD) is there anything I sould be looking for in an Amp? I'm in the market and was about to get an Arcam AVR 300, is it worth waiting?.
