So I've been playing back my collection of Buffy the Vampire Slayer DVDs ("The Chosen Collection").
When I open it from the DVD drive of a computer of mine, it works fine.
However, using a new DVD drive (an ASUS Blu-Ray drive) in another computer, every disc (so far) opens either on the first TITLE menu (not on the DVD menu, nor does it show the FBI warnings, etc), or it plays the audio from the first title menu, but doesn't show any video at all.
When I try playing these same discs with PowerDVD (v. 22), they play perfectly - they play the FBI warnings, then go to the main disc menu.
I've cleared all cached settings, but it still happens.
I don't seem to recall this having happened in the past.
Any idea what might be causing this?
