Ok, I don't know what I did, but I must have turned on VDR/MythTV. Everytime I select a movie, a remote is displayed on my DT366 webpad and my monitor flashes "NO SIGNAL". I cannot even leave the remote on my DT366 oribiter.
The remote has 4 color buttons (Red, Green, Yellow, and Blue), a keypad, a record button, a schedule button,etc.
Hopefully, I am one click away from returning to normal.
Anyone seen this?
Solved!
Somehow I installed VDR and once I uninstalled it playing movies works properly.
