I did some more digging and actually came up with a work around. It appears it just picks the tuner in the order it was added to the DVR. Since I have to add the Prime first to map all the Cable Card channels, the Prime is always selected first. Here’s how I got around that.
- Setup the DVR as usual and map everything the way you want.
- Shutdown Plex and make a backup of the database.
- Use an SQLite utility to open the com.plexapp.plugins.library.db file.
- Find the media_provider_resources table
- In this table you should find entries for all of your tuners. Check the uri field to see the IP if you have trouble figuring out which is which.
- In my case my first tuner was record ID 2 and my second was record ID 8. I changed them so that 8 became 2 and 2 became 8. Now when you view them in Plex the Extend is first and appears to be taking priority over the Prime.
Beware, you’re messing around with the main database for Plex so you may screw it up if you don’t know what you’re doing. It’s also handy to read the instructions on database recover for Plex if you have trouble.
