I downloaded v3.6 Eval of this S/W. It loads and doesn't crash, but it just plain won;t play a DVD. I know it looks at the correct dirve bay 'cos the access light flickers breifly when I click "play", but nothing else, nada, rien. It will neither bring up the Region Info menu. I have WinDVD and this works fine. Any ideas, or should I just bin the bugger? Also, just curious, but why do so many people list two or three SW DVD players e.g. TheaterTek, WinDVD, PowerDVD etc. Do they they each have unique strengths? I thought the "one to have" was the TheaterTek. Cheers.
