Comment(by ookaze at mail.ookaze.fr):

 For a temporary solution, eventuelly look here : http://mythtv-

 Basically, since 1st of june 2009, the HD multiplex for TF1, FR2 and M6
 send E-AC3, with extensions not supported in the current FFMPEG and as
 such, also unsupported in the current MythTV's FFMPEG.
 The FFMPEG patch surely won't be accepted for now. But at least it works
 for me, so I've made a temporary patch for FFMPEG (SVN from 20090620) and
 also one for MythTV SVN 20710, which is the one I use for now. And it
 works until now.
 Like I said in this thread in MythTV-FR, this is a temporary solution, as
 it comes with some problems.
 For example, I was forced to remove both AC3 and DTS passthrough as my
 receiver doesn't understand E-AC3, and it seems like when these options
 are activated, MythTV passes E-AC3 directly to the receiver.
 So I have decoded sound now. The patches is there :

 Also, these new channels include two sound streams most of the time, and I
 don't remember if we can select which one to choose by channel in MythTV,
 but it causes problems, as sometimes, we have one MPEG2 2 ch and one AC3 0
 ch (meaning no sound at all), and unfortunately MythTV always chooses the
 AC3 0 ch one, which means no sound unless manually selected everytime.
