Hang on a sec - didn't I say to play with AC3 Filter from the start? We had to go through nearly 20 posts for this?
...and what credit do I get? nada, zilch, nil points...
PS is it obvious I'm just trying to clock up my post count?![]()
yeah, its obvious

I did actually have AC-3 filter instalelled when I checked your first post, but I think the machine was so screwed with various versions of other codecs and filters (FFDshow audio, Cyberlink DTS etc...) that I lost sight of that and only got a result after a rebuild. Don't think I wanted to go through this full blown procedure I'd have taken a 5 minute fix two days ago if I'd been more on the ball. so thanks to DolbyDigitalTHX too
