Hi I was using Windows xp servicer pack2 in my computer but I have upgraded it to service pack3 before some weeks. From the day it was upgrade whenever I try to play DVD or any thing it gives me a error. I have tried same thing in my friends computer who is also using service pack3 and he is also having same problem. In error I get one message saying that it is not able to open the file and then there is a path will be given of that DVD. I donít know what the problem is occurring is their any chances of version incompatibility or anything else please reply me if anyone knows how to fix this problem.
