Hi all !

I have many problem to make my mythbox running fine. I run on my gentoo 
box both backend / frontend :

My Tv card is a Pinnacle 110i (software encoder V4l RTjpeg)

My first problem since i upgrade to 0.20 is a timeout problem when i 
launch liveTV.

2006-10-17 15:27:31.307 TV: Deleting TV Chain in destructor

So, i watch the source code to find the problem. It 's appeared that the 
timeout (quick) = 7000 ms or 7 sec and the backend hasn't finish its 
work before this time. That's why, i think after 7 sec the socket is 
closed and the liveTV can't start. So I patch Mythsocket.cpp to increase 
this timeout and the Livetv can start (after 9 sec in general), but now 
i have some A/V sync problem. Is there an issue more proper ?

Someone can tell me if my hardware is to light for this application 
(backend and frontend on this machine) ? A hardware encoder could solve 
this problem ? or there are many bugs or tips for doing work the 0.20 

Sorry for my poor english.

thanks all
