I have a fresh install of 810 Beta2. I set everything up on the VGA output at 1024x768@70. I have copied over several DVD .iso's (not ripped with LinuxMCE). Every one of them played great over the VGA output.
I took the system home, hooked it up to the TV and ran the AV Wizard changing to a custom 1360x768@70 over HDMI, UI2 looks great. Problem is that when I play any of the DVD's, it freezes with a black screen, and the DCErouter will reload after a few minutes. I re-ran the setup wizard again, same thing. If I run the AV Wizard and change back to VGA 1024x768@70 again the DVD's will play again.
I followed this article to get the custom resolution working http://wiki.linuxmce.org/index.php/Custom_Display_Resolutions
. I'm wondering if anyone know what other config files I should be looking at and if there are any log files I should check. Thanks!
