Comment (by Klaas de Waal):

 Have repeated the tests and it looks OK to me. No more sql errors and the
 chanid values are now as expected.

 About undeleting channels when they are found again in a scan, this is
 indeed something that can and should be done in the channel scanner. I
 have contemplated for some time the idea of creating a separate table to
 preserve the non-scanned data of a channel such as the icon path. By
 getting the data from a deleted channel or by undeleting the channel this
 problem is nicely solved.

 I think that mythtv-setup scanning in the current master is now quite good
 and most users will never need to delete channels. But accidents do happen
 and data that people have entered manually should never get lost. So
 keeping the deleted channels for a while looks to me a step in the right
 direction.
