[mythtv-users] problem with Fast Forward

[stef]

I have a problem when I try to fast forward some recordings at 5X or
above, mythtv just hangs after the fast-forward and return to the
recording menu.
mySQL tables are all clean (checked and repaired). I'm using ffmpeg.
I have this problem only with some recordings (everything is working fine
with some recordings). I don't know if it's a chance or not, but it's not
working only on CC recordings (close captionned).
My version of mythtv is : trunk.

Thanks for help,

stef
