Audio control function
Hi, i know that this is not directly in answer to your question, but I think there is a tangential similarity. though I am still using beta. What's happened with me is that resulting from I know not what, my IR remote stopped adjusting system volume. Oddly, it is most obvious on video things off the Net, like features from Frontline as well as Netlfix on line movies. Or things from emails. It won't adjust from the volume button on the keyboard either. In both cases the mute / unmute function works. Audio card is a Creative Titanium, but i don't think that has anything to do with it.
Interestingly, all of it works when using Cyberlink PowerDVD 7 Ultra, playing all forms of media such as music CDs, conventional DVDs and Blu-Ray. Also the result is the same from either of two drives.
