[mythtv-users] Changed monitor, no more playback...

Dear Ma,

thanks for the link, but none of the suggested solutions works for me.

There are some points that may sound interesting for you:

1) recording still works very well; I can watch every recording with 
Mplayer, Totem and such, but not with MythTV itself; never mind if the 
recording were made before of after the day I changed the monitor, when 
the problems appeared;

2) the backend never logs any error, whilst the frontend logs tons of 
"Audio data lost...", "Video is tot seconds..." and such.

3) I swear that everything worked until I changed the monitor: it got 
broken suddenly, and I took a glance to a recordin a few minutes before; 
  in the evening, I took another monitor from my daddy's house, turned 
the PC on again, and ... no more playback nor LiveTV from MythTV!

Best regards.
