This isn't happening on my system...ANYMORE that is because I don't run screensavers. However a friend of mine just got a new off the shelf system and he's experiencing this problem: while watching a movie on DVD the screensaver will come on as if there were no system activity. I don't know (and he can't remember) what program he's got for viewing DVDs but i remember I once had the same problem running PowerDVD. Like I say, I don't use screensavers anymore so I don't have the problem but was wondering if anyone had any clues as to how to fix this for him. We're both at work at the moment so we can't actually try anything until he gets home. However I've assured him that this is the place to get the answer if there is one to be had. Thanks in advance for your help.
