[mythtv-users] Some recordings play without sound in mythtv but are OK in other players.

[Philippe Crassous]

On myth .20, ome recordings (not all) made from an RTSP source (freebox 
recorder), play without sound on  mythtv but are OK with other players 
(on windows : VLC, Windows Media Player, Nero media player).

Transcoding the file fails, and I could not find a way to fix the file.

A faulty sample can be found at A 26 Mb recordings is available at 
http://philippe.crassous.free.fr/test.mpg

I would really appreciate your help for a workaround and maybe a fix.

Thank you

Philippe
