Mythtv won't record (failed to set channel)

[unplug]

The liveTV works just fine. It also record the program I was watching. But neither schedule recording nor manual recording worked. The error message from my backend showed that:

Error: Failed to set channel to 10. Reverting to kState_None
Changing from RecordingOnly to None

How do I solve this problem?

Lately, when people have has this problem there have been two solutions.

There is something wrong with your setup (even though liveTV works). You can delete all of your tuners (not one, by one, but all of 'em) and redo them.

Or the IP address between the backend and frontend was wrong.

I'll try to delete all of tuners although I only have one pvr-150 . I don't think there is a problem with the ip address because both backend and frontend are on the same machine and I use 127.0.0.1 with all ports in default.

Deleting all, in short, cleans out the database so you can start "fresh"

Double check, just to be sure.

Same situation here: Can't record anything I'm not watching, else the recordings turn up 0-sized. Removing all cards from the database and setting them up again borks, myth then no longer handles diseqc-commands (can't tune and can't scan anything but input 1). I have found that the diseqc_config table in database is empty after setting it all up from scratch (yes i do not accidentally leave the set-up process, cards are listed as they should afterwards). Then I have to restore a mysql backup of the entire database, and I'm back to square 1 (tunes all four inputs, but won't record unless i'm watching or just have been watching same channel).

I have tried to empty database totally and set all up fresh, most useless sunday I ever spent (would not scan or tune to the other three inputs). Both dvb-s card tunes and scans all four inputs on their respective diseqc-switch outside mythtv. I have two skystar2 dvb-s each connected to a 4-way diseq switch (Spaun). Same hardware setup has worked flawlessly with incredibly faulty and primitive software before and now works flawlessly with dvb-utils.

I deleted the database and rebuild it. Then ran through the mythtv-setup again and it seemed to be working. BUT...when I did a full scan, it only scan up to channel 13. What's going on?

[unplug]

I am so stupid. Under General ->Channel Frequency Table, I selected us-bcase by accident. After I selected us-cable, everything worked just fine
