Sync Lock looks good, maybe they've just switched to an encrypted
stream. If it's jumping in and out of lock then you have trouble but if
the lock is stable (typically 0x1f status) then it should be delivering
transport to the kernel demuxer ready for your apps to use.
Have you grabbed the entire transport stream to disk for analysis?
From experience, the ber, unc and snr values aren't always consistent
across products. I wouldn't put all of your faith in those. I tend to
rely on status (ox1f) as the best indicator of true lock.
Now that you have the hardware close to working, use dvbtune -i to see
if you can dump the pat/pmt packets.
