I'm not sure, I've never read the OpenCable standards. But from what
I've read about them they should probably get their own streamdata
which inherits from mpegstreamdata (or use mpegstreamdata for now).

Yep. I don't believe we are inserting these anymore, but there were
plenty of places we used to insert the wrong sistandard value.
I plan to write a dbcheck query which sets the sistandard to 'mpeg'
if it is either 'atsc' or 'dvb' and there is a zero or null ATSC
minor channel or DVB network id. Those with 0 network id's would
need to rescan to get EIT, but everyone whose systems were working
should be unaffected.
