If you have copies of channels on different inputs sharing a common
channum, then you will avoid having separate copies of the same
channel. You can specify your prefered input sources to ensure
recordings are more likely to happen on the tuner you want (i.e. if
I'm recording a movie or something to archive, I'll make sure my DVB
cards get it and not my PVR-350.

I don't think the xmltvid has anything to so with how mythtv schedules
- you are likely to have some channels with no xmltvid yet you can
still record from them. If you set up a manual recording, it uses the
channum, not the xmltvid to identify the channel (and then uses your
card prefs to determine which 'copy' of the channel to record.

Same again - have identical channel info but have each set of DVB
channels allocated to a specific input.

I don't have any answers of SVN - I'm still in the 'if it's not
broken' state of mind after getting everything running how I want it.
Perhaps an option to auto-add the channel but choose what range of
channum to give them would solve the problem generally, as users
around the world will be using all sorts of different channel
numbering schemes.
