This is the better solution, just make sure you rename any existing
"atsc" sistandard transports to "opencable" iff any of the associated
channels have (atsc_minor_chan <= 0).

The ATSC scanner should use "atsc" if there is a VCT, "opencable"
if there is no VCT but a video stream has a stream id of 0x80 and
"mpeg" otherwise.

I'll be glad to test the patch for the "atsc" vs. "mpeg" check,
and funaho (see #2579) should be able to test the "opencable"
check.

FYI I will only have cable for another week or so, so I won't
be able to test the scanner for a while after that.
