[mythtv] mythfilldatabase failed and also destroyed by schedule!

[Craig Rindy]

One final post to apprise everyone of the situation and to propose a fix for handling future scheduling service errors.

http://bb.labs.zap2it.com/viewtopic.php?t=134

But it doesn't explain why (or even acknowledge that) it seems to have worked for some (according to previous dev posts).  My guess is that the lucky ones just got their schedule while the service happened to be working for a short time amidst the earlier portion of the down time.

As someone mentioned on the users list, MythTV should probably be checking for "valid" data from the source before dropping all of the day's existing program data.  I think at least one show a day per channel should be a reasonable definition of "valid".  I could look into this if someone with more experience in this area doesn't feel like it.
