AGJ, I've been using MM because it seemed to be a cleaner and more seamless interface than the Media Center interface. However, I'm not married to MM and have installed the link you included, and using DVDFab VD it seems to work fine. However, my main issue, the low volume issue, is still occurring.
Racem22, I would prefer to stay away from codec packs, but in my desperation to solve this problem, I've simply been trying whatever is being suggested to me. So I did install klite, which includes the ffdshow, but again, it did not resolve the issue. Just to be clear, are you suggesting that you would recommend installing ffdshow, but not as part of the larger klite installation?
