Good evening,

I recently purchased a Nova-T DVB card with a view to running MythTv on my
machine, a friend who lives nearby has a system running using the same
card and it works well.

I'm running a Debian (testing) Linux box, on a 2.4.21 kernel, using a DVB
cvs checkout from last week.

Unfortunately, despite 'scan' being able to find [1] most of the channels
I think I should be able to receive, the most notable absence is of
ITV/ITV2/Channel 4.  Using dvbtune to manually tune to this frequency
gives:

james@neon:~/projects/DVB/apps/scan$ dvbtune -f 834167
Using DVB card "Philips TDA10045H"
tuning DVB-T (in United Kingdom) to 834167000 Hz
polling....

The bit error rate seems exceptionally large, which is suspect is (one of)
my problem(s).

Attempting to use dvbstream to receive a stream results in no (stream)
output:

james@neon:~/projects/DVB/apps/scan$ dvbstream -ps 512 650 -f 834167 -o

Does anyone know what might be my problem here ? - Is it perhaps the bit
error rate?  What is it about my signal/aerial setup that could be causing
such a high value ?

[1] I've attached the file 'dvb' which is the output from scan.
