I get the same with my DViCO FusionHDTV 5 Lite card.

I believe that the problem is with the DVB drivers -
I've written some software in the past that used the
DVB APIs, and the one thing that I noticed immediately
is that most drivers do not measure/report signal
strength in the same manner.  Some report it from
0-100 (percentage), some report it between 0-65535,
and others don't seem to report it at all.  Thems the
breaks when you're reverse-engineering.

I was reading somewhere (I think on one of the MythTV
lists actually) that eventually there will be a
defined method for reporting signal strength.
