The change that comes to mind is that selecting between DVB-S and
DVB-S2 mode now has to be done by MythTV as it has been taken out of
the drivers.  Previously, many drivers automatically selected between
DVB-S and DVB-S2 without being told to, and doing that actually
violates the specifications for the Linux DVB API.  Also, MythTV
previously used to use the DVBAPI v3, and now may be using DVBAPI v5.
