Thanks Kirk!

I was more interested in the digital signal since it's closer to an
all-or-nothing with tuning a channel. If I use my capture card and scan I'll
pick up about half the channels. Unplugging a splitter (with 2 devices
attached and thus boosting the signal strength) and rescanning will pick up
the remaining channels. I live in a city so signal strength is always an
issue... not sure what to do about it until the cable guys can come in with
a booster, etc.
