I installed PDVD 7.3 Ultra Retail Build 5105 over Retail 4617a (before downloading AnyDVD HD trial) to be able to play "The Day The Earth Stood Still - Keanu Reeves". The 5105 build: 1. PowerDVD closes silently - as if closed with mouse click, no messages, no errors - upon pressing play button irrespective of media type - dvd, hd-dvd, bd. 2. No available audio settings under "audio" tab of configuration - greyed out/disabled blank drop-downs. 3. No available region settings under "BD Region" tab - greyed out/disabled radio buttons, none preselected, 0 changes remaining. 4. CLDShowX.dll access exception: 0xC0000005. I have been dealing with Cyberlink so called tech support. Does anyone have/had this issue? Any resolutions?
