After reading other posts about some having success with ISO's and the latest patch from Cyberlink, I thought that I would try it out with my copy of Sunshine (BD+ disk). Well, here's what I found out (for my case atleast). 1) After updating to Catalyst 8.1, PowerDVD no longer incorrectly flags my hardware as being non-hdcp compliant. So that means that I can at least play my disks from the optical drive. 2) I get alot of studdering playing Sunshine from disk. I get no studder that I can detect playing from hard drive (PowerDVD version 3304) and the sound defaults to DTS Surround. I know its debateable, but I think DTS sounds soooo much better and louder than Dolby 5.1, at least with this soundtrack. The only drawback playing from the hard drive with this title is that I cannot watch chapter 16. Trying to navigate to it in any way will lock up PowerDVD. I can watch 15 and 17, but no 16; weird!!! 3) Making an ISO with ImageBurn using Read mode and mounting in Daemon Tools does NOT work with the latest version of PowerDVD. You get the message "Unsupported format in drive (drive letter)". If anyone knows the trick to making this work with some hidden setting, please share. It does not work for me and i'm going to assume most others. So while I am happy that my hardware is no longer incorrectly flagged, the disk performance is horrible compared to hard drive performance even with the newest version (and yes, i checked to make sure hardware acceleration was on...it was). So my only real alternative is to stick with 3304, which works with anything, including BD+ (Sunshine, Spiderman, etc) and forgo Profile 1.1 features. I only really just want to watch the movie anyway.
