I've been made aware of the updated version in Hg... The version that got into 
Fedora 8 is utterly hopelessly wrong though. Frequency offsets are 'sort of' 
right, but the modulation mode and FEC settings are out in the woods for a few 
muxes.

What I found odd was that my Freecom USB stick wouldn't lock to the frequency 
if the offset had been added/subtracted already. The Hauppauge Nova-TD stick's 
first tuner (MMCX? connector -- the little ~3mm thing) doesn't mind, but the 
second tuner starts losing muxes if the frequency is strong.

What's odd is the first tuner sees more on Linux than it does on Windows, and 
both tuners see different things, and on Windows both tuners see the same, but 
don't pick up Film4 (698MHz, C49, Mux D). I find this odd because by all 
rights Mux A (650MHz, C43) should be disappearing as it's the weakest... this 
would seem to rule out signal strength issues. In fact, wiring up a masthead 
amplifier just made scandvb spit out "WARNING: filter pid timeout" without 
finding any channels.

Most peculiar.
