Yes, I am still digging around this one. I was looking through the
code today and decided
that the issue is that the cable virtual table returns 2 and 1 for the
major and minor. But
that is not what what it is that the signalmonitor code is looking
for. It is looking for the
actual major and minor. Does anyone know what part of the ATSC/cable
virtual table will
return the right information? Do you think it would be at all
reasonable to modify
VirtualChannelTable::Find() to look for this info when called? Maybe I
should ask on the
dev list?
