I confirm AC3 filter works fine under Win Seven It should do the trick, but if You still have some problems - try ffdshow with libavcodec or libev52 :)

If anyone else has this issue (I did) - just know that Ac3 Filter Full version would not work. It made the video unwatchable (choppy). I uninstalled and tried ACFilter Lite and it is perfect.

A final option for all you guys may be to use VLC player instead, as it isn't reliant on codecs at all.
You'll be surprised at all the ripping, converting, capturing, and streaming functions it has as well.
