Hi, hope this is of use to someone... but have finally come up with a winning combination. Have been messing around with my HD setup for weeks. However using powerdvd 7.3 (build 2911 I think) it was still hit and miss with some HD-DVDs. I've installed the latest version of Nero Showtime with the HD/blu ray plugin. For some reason, it recognises the xbox 360 drive but produces an error because the HD-DVD has AACS protection. However, of course anydvd strips out this protection and lets my HD-DVDs play great. The info in nero showtime shows 1080 output at 23.8fps and its let me watch the HD-DVDs I couldn't get to work with powerdvd. My sata blu-ray drive should arrive this week and can't wait to test that too. Am just purchasing my Anydvd licence now (hopefully my matrix boxset will arrive today).
