Well, as you may recall from my original posting, it all works great 
with other programs, just not with MythTV - so the frequency tables and 
modulation type are definitely correct.  I have tried with 'open DVB 
card on demand' and without, and it makes no difference in this case.  
Lengthening the timeouts doesn't help either - it consistently shows 0% 
signal on every channel, or occasionally, some random percentages, like 
29% signal, and 4% S/N - but in those cases these random number will 
stay the exactly same for every channel as it scans, which doesn't even 
make sense.


I could try downgrading the kernel to the version you say was working 
for you maybe...
