MSI Digivox ATSC Tuner stick-won't scan QAM channels

I am using 2 digivox ATSC tuner sticks with the latest build of J River Media Center (QAM capable) as the host software and that setup works great to pull in my local OTA channels using one of the Digivox units connected to an attic antenna.

BUT, my second Digivox connected to Comcast will not scan any clear QAM channels no matter what I try. Comcast told me they use Standard frequency on their Clear QAM, but I have tried all frequencies (HRC, IRC, etc, etc) just in case. Ideas?
