I recently upgraded to JRMC17, and I've been having problems with video ever since. The main issue is: some DVD's will play with no audio, and others just give a region code not supported error message. I'm pretty sure the following is related because of the time it started: my Sound > Playback tab will drop my second monitor as a device; is says "not connected" even though it is. I have to go into the Display Menu and re-do the Monitor settings (Duplicate / Extend Display). Also, I have selected Auto Play to "Let Windows Handle", and deselected MC in Windows; yet JRMC17 automatically opens when I insert a DVD. I chose to transfer all the settings from Version 16 when I upgraded, and none of these issues were present on that version. I mainly use the program for audio playback and storage, and once I confirmed that this was working properly, I deleted Version 16, so going back to those settings is not an option. Can anyone out there help me?
