I've got a few movies with PC Friendly, and my computer would lock every time I tried to play the DVD using the PC Friendly software.
Also, I don't understand why each movie said that I needed to install the PC Friendly software, even though I had already installed it for another movie I had. Is it really different for each one?
Anyway, if I play the movies with the software that came with my Hollywood Plus DVD decoder card, then I'm OK and have no problems. I have now removed the PC Friendly software completely.
