At 08:13:47.663 in the BE log, the PMT for the channel that you're
tuning shows that it's encrypted. Since the TeVii S660 doesn't include
a CI slot then I assume that you're using some other form of decryption
- sasc-ng? I'm aware that 'house rules' forbid further discussion here.
You should take up this problem with the decryption provider.
Everything else looks fine in the log, so your tuner is working OK.
