[mythtv-users] Lacking TV signal

[Per Jørgensen]

Hey techie's.

I've setup "under the stairs" solution at home.
I have only one tunercard in the master server - A Hauppauge PVR500 
(dual tuner)
I have 2Satelite recievers connected to each tuner using the RGB.
I have GB LAN network in the whole house.

But when seeing the LiveTV And also recordings I have the signal lacking 
and jumping all the time.
When I take a Satelite reciver and connect it directly to the TV there's 
nothing.
There's also no problems with seeing DVD's, video's etc.
Can I do something about that.
The Machine Running the Backend is a
Dell GX320
3.0 Pentium4 Hyperthread
3GB RAM

And it seems like it's the signal between the reciever and PVR card - 
where it goes wrong.
But when viewing the LiveTV - I constantly gets this in the logfile if I 
chose to log everything:

But 1time pr 2minuts - the Signal Freezes - for 2-3 sec and then 
continues ??

What can that be - and what can I do to solve this problem!
