LiveTV order same as schedule order may be default as well, I just don't recall well enough. The more I think about it the more likely I think it does default that way...

Schedule Order and LiveTV order are in MythTV setup then Input Connections then select a tuner then next page and amend Schedule Order and LiveTV Order. So no need to fiddle the database directly.
The specific values are not so important, more so the relative value. I would probably do this (below) but replacing 6 with 2 (which may be more logical / sequential for some) or any other number greater than 1 would work equally well. Don't ask me why I chose 5 for mine, must have run out of fingers and toes at the time...

To be honest I don't think the ordering is causing your problem, but the recommendation is that if all the tuners are equally functional then that should be reflected in the order priority.

If by this you mean essentially get the scheduler to prioritise the grouping of recordings to a tuner where the tuner is already tuned to the matching multiplex then no. There has been a bit of debate in this list previously with a number of proposals provided but each had its pro's and con's.

I went looking and couldn't find how to do it either, although I am sure instructions have been provided previously (without direct database manipulation). Maybe someone else will jump in.
