Hello, I've updated the AC3 tool. What's new: Before I start with AC-3 transmission I delivers several pause-burst frames to suppress the DD reciever glitch during PCM->DD switch. http://www.fiesel.de/download/a3patch-0.2.diff.gz (previous one is renamed-> a3patch-0.1.tar.gz) (Thanks for the hints how to make only one diff file) Wolfi
