The reason for that is the Pal and presumably other CECBs can tune 2-69, so when it hits two signals with the same ID on different frequencies it can't assign both the same PSIP numbers. So it picks one, I've no idea how it determines which, and drops it up on 70 where there shouldn't be any real channel.
It'll also bump a new channel that maps to a PSIP channel already in use about half the time.. the other half it bumps the channel that was occupying that PSIP assignment.
Gets annoying when you get a heavy tropo night or three having to go delete dozens of channels that don't tune and
the bumped channels that you want on that PSIP number and then
rescan to put things back how they were...
The Pal DVR has the exact same behavior too, if anyone's curious. The thing that's strange to me is the DVR is supposed
to scan for new channels like that, but from what I know the Pal+ only scans when you tell it to.. yet it still happens.
