Ok, so I have read the guides etc.

WinXP SP2, trying ot use FFDShow to REALTIME encode the AAC from 5.1 MP4 ->ac3 for HTPC stuff.

So I get to work - sort of. The reciever sees 5.1 (3/2+LFE). However, the speed is "fast" - like it is 1.5x or soemthing. I am makning sure I resample to 48k, triied both libfad2 and realaac for codecs in ffdshow, tried waveout or directshow etc.

Anyone see this? I am sure this is simple. If I disable ac3 output (640 btw or 384 same pproblem) the speed is normal.

So I have done a complete uninstall and reinstall. Still no luck. Again, if I use the analog out (disable AC3 out) all is works fine.
