[MPlayer-users] Re: AC3 5+1

#1, ALWAYS keep mplayer mail on the list! Next time I get mplayer mail
addressed to me personally it goes to /dev/null even if it's a valid
point or relevant question.

This means it's 5.1 AC3.

This appears to mean mplayer is playing it for just 2-channel. Like I
said, mencoder might have put bogus numbers in the headers, but if so
I'd be surprised if no one else had noticed such a bug before.

Anyone else have comments on this? (BTW if you just mail to me, no one
else can read your mail so no one else can comment!)

Frame drops??? Are you sure you don't mean duplicates? If you get that
message, it means you need to use -ofps 23.976 if you're encoding.
(This is in the fine manual.) If it really is drops ("skip frame"),
then something very strange is going on, and you should send a proper
bugreport to mplayer-users.
