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).

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.
