DVB-C, distortion on some channels.

Hello,

I have a Technotrend C-1500 card, I am experiencing some
interference/distortion in image and sound on many of the channels, .
when I experience this the mythfrontend dumps lots of errors see below.
The strange thing is that some channels it occurs all the time, while
some channels it occur less often and some channels are entirely fine.
It think the problem is with the channels that are on the same
multiplex, but I am not sure. I'm using kernel 2.6.23 that I built
myself and with the latest v4l-dvb from CVS. Through I have the same
problem with the previous kernel. The Signal Strength shows around 55%.
I am using MythTV but I have the same problem with Kaffeine. To make
sure it wasn't a poor signal that was causing it I tested with the
decoder provider by the cable company and it was fine using that
decoder. Could my card be defective even though some channels fine?
