Slow playback with avs

[Buffman]

Hello...

I'm an avisynth newbie, but i'm having problems playing back a 1080p wmv file with alternative soundtrack.

If I playback the clip using zoomplayer I get full fps, however if I play it back with an avs file I get just a few frames per sec. I've read through the FAQ and searched the forum, but haven't come up with anything...

My avs file looks like this -

LoadPlugin("ac3source.dll")
DirectShowSource("shrek.wmv","audio=false")
AC3Source("shrek.ac3")

I tried creating a graph file, removing the renderers but got an "grf unsupported format" error when playing it back. Although I just realized maybe i'm not using the latest version of avisynth. When I get home from work I'll check it out.


Any ideas what's going on here and how to correct it?

Thanks for any/all help!

1) Don't use AC3Source. It downmixes incorrectly.

2) If you want to downmix see the docs in directshowsource.

Make a script

Version()

what version does it give?

Yes - use AC3Filter, the Directshow plugin to get best possible sound from your AC3, if importiong via DSS.
