I don't use the DVD Player all that much but I did encounter something
similar to what you describe when I initially installed the Cat 3.8 and
MMC 8.7 drivers while testing. After I rebooted the system a couple of
times, I haven't encountered any DVD Player hang if I click within the
player using my mouse (setup commands seem to work ok, right clicking
the mouse, etc).
However, I notice that if I muck around with the size of the screen,
click on different settings (while playing a DVD) or stop the player and
restart, the screen goes black (the DVD continues to play because I
still have sound); the only way to get a DVD picture, I have to close
the app and restart it...
Not sure if these are new issues or not (I rarely use my DVDROM drive to
view DVDs).
