A MythTV DVB channelscan creates a list of channels with channel numbers
defined by the Logical Channel Descriptors in the NIT.
A DVB-C capable HDTV processes also the HD Simulcast Logical Channel
Descriptor which defines the correct channel number for channels that are
transmitted both in SD and in HD quality.

For instance, MythTV puts channel "NPO 1" at number 1 and channel "NPO 1
HD"(HD version of the same channel) at number 925.
My DVB-C TV does the opposite; channel "NPO 1 HD" is at number 1 and
channel "NPO 1" is at number 925.

The attached patch does add the processing of the HD Simulcast
descriptors.
The result is a channel list that is identical to that of my TV.
This is tested with the DVB-C signal of operator Ziggo in The Netherlands.

Comment (by kmdewaal):

Note that the patch set also contains one unrelated modification; the
statement "info.is_opencable = true", executed when an SCTE Registration
Descriptor is seen, is commented out.
In the Ziggo DVB-C signal there are SCTE Registration Descriptors in about
10 channels but it is not correct to classify these channels as opencable
instead of DVB.
