The goal of the MythTV project was to make all of your digital media
accessible through an integrated living room interface, and in the early
years it absolutely achieved that goal better than any of the alternatives.
The heart and soul of MythTV has always been the PVR, though, and most of
the considerable development energy in recent years has gone into
maintaining MythTV's position as the best PVR money can buy.
To that end, MythTV heavily leverages the fact it is the "recorder" of the
PVR. The backend decides what recordings are available, where they are
stored, and what format they are stored in. It has access to structured
metadata about those recording before they are made. To make things run
smoothly, though, it needs unrestricted access to your tuner devices and
Mythbackend is the heart and soul of MythTV, and while the various myth
plugins share a frontend interface and access to a database with
Mythbackend, they are seperate entities that simply have not recieved as
much attention as the backend over the years.
As for specific suggestions, the answer to your problem is to get your
movies into the recordings directory/table and out of the MythVideo ghetto.
I believe there are tools available that will help you accomplish this, but
I'm afraid I can't offer any specifics.
