Dear Friends, I am trying to watch commercial DVD's. I wanted to use Niceplayer.I have tried VLC it works, but my machine is too slow. Niceplayer gets lots of praise on the internet.I can't figure out how to use it. It says just drop the DVD icon on Niceplayer, that doesn't seem to work. It sees the file, but all I get is a black screen. I have installed recommended codecs( Perian) but its no help. I have scoured the internet for advice to no avail. Can you help? Thanks.
