Hi,

I've been having some problems with my Nova T 500 so I decided to do  
some more sniffing around to see if I could turn up the reason for  
the problem.  I decided to run tzap and study the output, here's what  
I got:

beastie:~# tzap "ABC TV"
using '/dev/dvb/adapter0/frontend0' and '/dev/dvb/adapter0/demux0'
tuning to 226500000 Hz
video pid 0x0200, audio pid 0x028a
status 07 | signal 83ea | snr 0000 | ber 001fffff | unc 00000000 |
status 1f | signal 839f | snr 0000 | ber 00019a90 | unc 00000ad0 |  
FE_HAS_LOCK
status 1f | signal 840c | snr 0000 | ber 000057a0 | unc 00000000 |  
FE_HAS_LOCK
status 1f | signal 83e8 | snr 0000 | ber 00006520 | unc 00000000 |  
FE_HAS_LOCK
status 1f | signal 83eb | snr 0000 | ber 0000a9c0 | unc 00000000 |  
FE_HAS_LOCK
status 1f | signal 83aa | snr 0000 | ber 00008250 | unc 00000000 |  
FE_HAS_LOCK
status 1f | signal 83a5 | snr 0000 | ber 0000e9c0 | unc 00000000 |  
FE_HAS_LOCK

Now, from the Wiki (http://www.linuxtv.org/wiki/index.php/Zap) it  
doesn't look good, I think my snr is wrong and my ber is too high.   
Can anyone confirm?

How would I go about finding the problem if there is one?

Cheers,
Dan
