What version of myth are you running? And what kernel version? And what
playback card?
I'm running 0.19-fixes revision 9591 from the 1st on a 2.6.15 kernel with
a 128M nivida 5200 AGP.
I'll check the signal strength tonight. It was on the low end (good
signal end) of azap's specs, and
I think Myth typically displays 98% signal strength when changing
channels, but I'll have to check
the backend logs to be sure.
