I backed up the db, then did a rescan, deleting existing entries
first. It found 3 channels (all on one frequency), but it was like
it kept finding the same 3 on every frequency. The status pane said
adding, then said updating for the 3 channels over and over. They
all had 159 in the freqid column - I think thats the last freq on a
cable-high scan. I did the scan again and it seemed to be the same.
When I started the backend and tried to watch livetv, none of the
three would lock.
So tonite I redid a dvbscan and it looked pretty much like its been
for the last couple months. Then I powered off the machine, powered
back and did a delete rescan again. This time I got no channels
found. I just restored my channels and multiplex from the backup and
I'm back to where I was 2 days ago. I have no idea why the scan
didnt work, but its the first time I did a rescan with 0.20.1.
