I recently upgraded from PowerDVD Ultra 10, which was working OK, to 12 (2625). 10 was able to play my 3D Blu-Ray titles just fine. With 12, it switches the graphics card output into 3D (as verified by the info screen on my projector), but the output is either a solid blue screen, or a screen with vertical stripes, and the computer locks hard such that I have to reset or power cycle it. 2D Blu-Ray titles work fine. 3D output works fine from games.

Also, when playing 2D Blu-Ray titles, it asks me if I want it to change the output format (apparently from 1080p60 to 1080p24), but if I let it change it, the playback winds up only updating the screen about 5 times a second. If I leave the output at 1080p60, playback seems fine.

I tried upgrading the graphics drivers to the latest (AMD 13-4), but it didn't fix anything.

I uninstalled PowerDVD Ultra 12. When I try to reinstall PowerDVD Ultra 10 I just get a dialog that says "This patch is only for versions of PowerDVD 10 that support the play back of Blu-ray Discs."

Since I can't get PowerDVD 10 to reinstall, I also can't reinstall the 12 upgrade, since it doesn't find 10, so now I can't run PowerDVD at all.

I have legitimate purchased product keys for PowerDVD Ultra 10 and for the upgrade to 12, but I can't even get the installer to ASK me for the keys.

I'm using Windows 7 64-bit on an AMD Athlon II X3 450 (three-core, 3.2 GHz) with 16 GB RAM and a Radeon 7770 card.

Update - I managed to get PowerDVD 10 installed again. Even the "Cleaner" programs in this forum didn't seem to get rid of all of the outdated stuff that kept it from installing. I had to delete some folders and registry entries manually. Now I can watch 3D Blu-Ray just fine with 10. Wish it worked with 12, after I paid $49 to upgrade. Not willing to pay more for 13 until there's a patch to 12 that works.
