I have not been able to play any DVD movies on my laptop with InCD4 installed. I downloaded and installed version 188.8.131.52 and it didn't help. My computer is running Windows XP Pro SP1 and has a single DVD-RW drive. I have to remove InCD4 completely in order to watch DVD movies. But the strange thing is that I'm able to watch DVD movies that I created without any problem. Is this another bug in InCD4 or it's just that I did not install it properly? Please help!! Thanks.
