Is anyone have problems with their HDDVD backups with audio over SPDIF with Vista. I have an e6600, 8600gts, 1 gb of memory, PDVD 7.3 with latest patch, creative audigy 2 NX external sound card, and vista ultimate. The problem is minor but there. Every ten minutes or so, the sound will cut out for a split second. This seems to happen with Universal HDDVD releases. Warner and others seem ok. Specifically, I had a problem watching "the hitcher" on backup using latest version of ANYDVD HD. Any ideas?
