Ah. I think I found it…AME has a decode problem.
The source file is AC3 5.1 and plays just fine in Windows Media Player.
Here is AME’s (CS5.5) source data-mining and the “Stereo” mistake…
I guess I need to find another 5.1 test file to do my testing.
Zac, etc I can email you the 2.2Mb file if you want.
