I sent out test patches to address this very issue ages ago, but nobody has ever
responded with any test results...


The current code in the kernel will (or should) behave as follows:

One RF is used for analog + digital cable (QAM256)

The other RF is used for OTA VSB only.

One of the patches in the link above should change the behavior to reflect the following:

Analog will always use one RF, and digital, regardless of VSB or QAM, will use the other.

At the time I wrote the email, I wasnt sure which patch was correct, so I provided two
for testing.  One will work correctly, and the other will probably force all tuning to
use the single RF no matter what.

I do not have an ATSC110 to test this with, so it is up to you guys to test the patches
that I am providing, and make the appropriate changes to them as necessary.

Actually, the FusionHDTV3 Gold-Q also has two rf inputs, in addition to
the ATI HDTV Wonder.

I hope this information helps you... PLEASE respond with some feedback.
