I just bought a new-to-me, used M500. It appears to work normally except for one thing: if I insert a Blu ray disk into the M500 and close the tray while viewing the movie list on my monitor, nothing happens. I never get the "disk-in-player" pop up. If I hit the import button, the disk imports. The M500 appears to work fine in all other respects except for the catalog feature. When I first got the player I connected it to my monitor and it played movies fine. It is not currently connected to a monitor. Here's my setup: I have a premiere 3U server, an M700 and an M500. The M700 is connected to input 2 of a Co-Star (I also have an Encore system). The M500 is only connected to the network. All of these are properly grouped together. Is there some setting on the M500 that I need to change? Does the M500 need to be connected directly to a monitor either by itself or to the Co-Star? Is there perhaps some setting on the Strato player that is preventing the popup?
