Hi there!

I've finally managed to get my system sort of running. Trouble is, my 
live TV is jittery and horrible. To me, it looks like the signal is bad 
but when I change channel I get a signal of 61% - which isn't bad is it? 
I'm sure when I had the box in my living room it was about that.

I testes CPU usage with top and mythbackend was only using 10% of my 
CPU! So it can't be that can it?

The antenna is in the same position I have just re-cabled from my loft 
into my garage. Could it be bad cable? Are there differing qualities of 
UHF cable?

Please help me - I'm so close!!!

Oh, so I can't be accused of not giving enough info:

backend: 1Gig CPU, halfGig ram, Debian Etch, kernel 2.6.22

frontend: 1.8 Gig CPU, halfGig ram, ubuntu 8.04

mythtv 0.21

Here's the messages I get from the front end:
