Audio out of sync on some video files

[Anthony2816]

I've never used the filter option, so it's whatever the default ones are.

How do I tell which ones are being used? The non-grayed-out choices are:

Default DirectSound Device
MPEG Video Decoder
MPEG Audio Decoder
Advanced

I kind of suspected that the file is bad, although I do seem to get quite a few of them. Most are downloaded TV episodes...
