If the signal strength you're referring to in mythtv is the one that
momentarily appears in the OSD when you change channels, I think that
(at least in 0.20.2 with my HD-5500 cards) there might be some sort of
timing issue with the way mythtv reads that strength.  Mine sometimes
even shows zero.  However, if I actually display the strength by
either using the F7 key in mythtv or using a separate program (I use
femon a lot) it'll be anywhere from 60 to 95.
