Colt,

I have the HD-A1 using the 990's dvi switching, and saw similar problems when viewing two disks, Van Helsing, and Assault on Prec 13. They were both rentals from netflix, and I am pretty sure the problem with Assault was a scratch...there was a loud pop before it froze, and it really froze. Could duplicate it at same scene. I have watched two other rentals (Dukes and Phantom) without any issues, and the one hd-dvd I purchased, Serenity, played fine without any problems. I think/hope the issues are disk related, but not sure since my sample is pretty small now...but have read that the HD-A1 is real sensitve to disk imperfections.
