I am in long beach california on charter cable and have this same problem.
It seems to be the cable provider. I did some investigation and it appears
the cable company is sending 0 for both the atsc minor and major channel
numbers in the VCT tables. mythtv freaks out with these because it appears
there are multiple program numbers that map to the same channel. I wouldn't
necessarily blame mythtv for this, because it looks like a deviation from
the standard on the cable companies part.
I modified my source tree to ignore the VCT, and now the channel scanner
finds every channel using the the PAT (or was the PMT?), I just have to do
the manual processing of deciding which program number is which channel. I
assume there is some other multiplex with some other complete table (whether
it is a VCT or not) that has a list of all the channel numbers and program
numbers. I just haven't spent the time evaluating all the multiplexes that
my cable company provides.
Daniel is working on a new channel scanner, I am not sure if it will have
the ability to ignore broken ATSC tables or not, but I remain hopeful. :)
