I'm using PowerDVD 8.0.1730.50 and noticing some odd behavior: With either a Blu-ray or a DVD disc inserted, when I press the play button the disc starts spinning for a moment, the play button turns gray, but then nothing else happens. PDVD remains in this state indefinitely and never starts playback. But if I press the ENTER key on the keyboard, the disc will start playing.
I never had this problem with earlier versions of PowerDVD running on the same hardware.
Any idea how to fix this?
