Comment (by Rune Petersen <rune@…>):

 great idea, I have improved your patch slightly for DVB, so fixup isn't
 calculated if channel lookup is negative.

 It gives a slight measurable improvement in CPU usage for 'mythtvbackend'
 and a noticeable improvement in CPU usage when the EIT scanner is running
 in the background.

 I am running this on a 700Mhz ARM system, so the improvement may be harder
 to notice on more powerful systems.
