I use a script to reinitialize my channel table it it changes.

mysql -u mythtv -pmythtv -hnordtv mythconverg << EOF
update channel set
 contrast   = 20100,
 brightness = 34275,
 colour     = 32768,
 hue        = 32768
 where chanid < 2000;
update channel set
 contrast   = 26500,
 brightness = 30750,
 colour     = 32768,
 hue        = 32768
 where chanid > 2000;

...[etc. then tweak individual channels]...
