this is a problem with mplayer, it doesn't know how to properly handle
AC3 in DVB streams.

I don't understand why MythTV is having a problem with it. My two
A180's have been working fine. Some other folks have said they've been
seeing audio sync issues with HDTV, so it may be related to that. Do
you have any other HD sources?
