Firstly, what is PCFriend, if it is one of those anti-crash programs, I would disable it and see if that made any difference. If the error message still appears then you need to make a note of the number 017f:bff7d76b, if it is exactly the same every time then you could have faulty memory as this is what an invalid page fault generally means.
It may not happen when doing anything else as the DVD software could be the only program that uses this area of memory.
