I realize that this thread is for version 11, but the key reason I stopped using version 12 and gone back to 11 is that version 12 aborts constantly when playing back high resolution audio tracks such as DTD-HD MA or DOLBY TRUE HD audio tracks. Originally this was thought to be related to using INTEL HDMI audio, however when I went to an NVIDIA HDMI audio card with different driver and discovered the same problem, I pretty much gave up on it. This was to be fixed in this latest version 2428 but it's not. The problem is still there. I have now given up on the software and considered the upgrade a total waste of money.

Do you mean it kept going or flickering "black screan? When I started using PDVD 12 (trial), after this big issues with PDVD 11, I was getting a "constant aborting" or contsant blacking out. I discovered it was an issue with the video setting with PDVD 12. In videa settings "advanced" (i believe) there's a setting for "Interveaving" on or off, after turning this off, the problem went away. Full DTS-Master audio works great, also.

Hope it works for you also.
