Thanks for the reply!
- 6th-gen Intel/Skylake i5-6200U @ 2.30GHz and 16GB of memory.
- Both integrated Intel graphics and a discrete NVIDIA GeForce GT 930M (as is often used in gaming laptops)
- Windows 10 Home (version 1607) OS Build 14393.447; 64 Bit
This PC was working with the latest version 20 build for about a week with "Red October HQ" with little stress on the system (based on the task manager.), essentially I just tweaked/made sure the default graphics being used with Media Center was the NVIDIA GeForce GT 930M, which I seemingly can verify with the NvGPUStateViewer64 program.
Again, the other day, Media Center started to exit after I selected a video to play. No error, just the program ends and the desktop displays.
Windows 10 (not so wonderfully by the way...), now updates the computer automatically and there is no longer a simple option to defer or choose updates, so there were a few MS updates but none looked like they updated the video driver.
Based on your response about video driver suspicion, I also uninstalled the NVIDIA card and then (re)downloaded the latest GeForce NVIDIA drivers, and installed.
I can still launch in "Red October Standard" but "Red October HQ" now results in a very long black screen followed by the message "Media Center 20 has stopped working. A problem caused the program to stop working correctly. Windows will close the program and notify you if a solution is available."
I also now notice that in the NVIDIA control panel, although I can set the "global settings" preferred graphics processor to the "High-performance NVIDIA processor", I can no longer specifically customize JRiver Media Center 20 to the NVIDIA processor. It shows "Integrated graphics" and the "remove" and "restore" buttons are grayed out. I am able to assign other programs like Kodi to the "High-performance NVIDIA processor" preference.
Previously I tried to uninstall the JRiver Media Center program and selected to clean all registry settings, had a new license code emailed to me and reinstalled, but the same error happens.
As noted, if I change the video mode to "Red October Standard" videos play, but have horizontal lines and choppy and it is not a usable setting.
Also as noted, after an interact forum search I also tried to download a new/latest version of madVR0911 and ran the install, but I am not really sure it did anything, it said no files were copied. I was able to look at the config and other tools by running from the installed directory.
