Audio Buzz in WMC and WMP but not VLC
I have been using WMC7 for a number of months now with no real dramas. I tried to watch a movie (avi) that I have previously been able to watch. There is a loud buzz/crackle noise when I try to play it now. When I first noticed this I tried to play it with WMP and it worked fine... A little later on when I tried with WMP again it was doing the same buzzing noise (I hadn't changed any settings or drivers or anything)... VLC still plays the file correctly with no buzz. I have tried a few other movies and so far have only found one other avi that this also happens with.
I have tried to update the sound card drivers to latest version but this has had no effect.

Writing application: Nandub v1.0rc2
Writing library: Nandub build 1852/release
Writing library: XviD 1.2.0.dev47 (UTC 2006-11-01)
Both Nandub and VirtualDubMod always had a lot of problems with AC3: Nandub not being able to correctly set the number of channels, adding tons of junk into the file; it cuts the stream right in the middle of a frame, adding junk to the end of one part and the beginning of the next, as well as at the beginning of the stream if there is a A/V delay that needs to be calculated. And besides, AC3 audio gets split across interleaves, no matter what interleave parameters you use.
I don't think that this is a problem with your version of AC3 installed, but just in case you didn't update recently, go to the AC3 website and download and install the latest version of AC3 filter... Just in case, you might also download AC3file.
If the buzzing sound appears again, you can still play them correctly with VLC, or, if you own these movies, consider updating your rip settings to H264 instead of the crude XviD. Handbrake is the best tool for this, if you decide on this approach but can't get the hang of it, I'd be happy to share a few tips
