I was thinking along those lines myself, but the "magic option" method is a 
quick hack to allow it to be disabled in the meantime.  I haven't really 
gotten into the mythtv GUI, so I have no clue how to go about offering a 
proper option for this (I'm assuming this should be done on either a per-card 
or a per-input basis).

I'm really sort of confused by the large CPU load this is causing - the 
difference is in the range of 1-3%CPU on my system.  It may be that the code 
is less optimal on other architectures, which is what I was hoping this 
modification might correct, but it doesn't look like anybody has tried it
