Hi Andreas,
I've done exactly the same .. I recorded some movie ... (nothing special ..
and NOT 5.1) and played it with ac3dec without any problem ...
I don't now anything about size and sync .. I just can tell that it works
...
Greetings Stefan

Hi Stefan,
i have decoded a 2/0 AC3 Stream (the standard Stream from pro7 television).
Pherhaps you has recorded a 5.1 DD Stream from a movie ?? My stream is
wrong. From the sync to the next sync bits there is more room then the
framesize told me (14 Bytes).
Andreas

What kind of Stream have you tested ? The recorded stream from Pro7 works
as fine as a ac3 stream from a dvd for me (ac3dec from the actual alsa cvs)
I can play it raw to spdif and can decode pcm. Only Cinedom dlx makes
problems.
