The post 12618 problem only affects scanning on the ATSC side of things.
Your post was unclear: do you have TWO different zap2it channel lineups?
When you switch modes it is as if you swapped cards completely. So you
need a lineup distinct to NTSC channels. Your error message about wrong
modulation implies to me that you are trying to tune an NTSC channel,
using an ATSC-channel tuning method (because myth thinks it is dealing
with an ATSC channel). That fails, of course.
If you HAVE defined 2 lineups, it sounds like your NTSC channel listing
has the same modulation value as the ATSC....
For NTSC tuning, your card would not (properly) use the dtv_multiplex
table... which is the one place where modulation appears. (It should be
qam_256 for digital cable: in mysql:
select modulation from dtv_multiplex;
