Thanks to all for your comments. I'm learning all the time but sometimes the learning curve is a bit too steep.

I set up an experiment to confirm an idea. I manually scheduled 3 overlapping recordings, 1 for BBC1 (multiplex 1) and 2 for UTV (multiplex 2). Everything worked as specified. Apparently it is acceptable in MythTV to make 2 or more simultaneous recordings of the same channel. I therefore conclude there is no good reason why padding should cause conflicts with "back to back" recordings. It would require a small (I think), revision of the code. Virtual tuners only exist in software, so the software is already capable of sending the same stream to two (or more) distinct recording files. There is a downside - if you had 3 channels with simultaneous "back to back" recordings, there would be a short time when you could have 6 recording files open at the same time, but then six virtual tuners would have exactly the same effect.

Having reached that conclusion and, since the code is as it is, I decided to reset my system to 5 virtual tuners per physical tuner. To keep things tidy I deleted the 2 capture cards and then reinstated them with 5 simultaneous recordings on each, and now my system is broken. Instead of the 8 virtual tuners numbered 1 to 8, I now have 10 virtual tuners numbered 9 to 18. "Tuner Status" says "Tuner .. has an error", "Watch TV" says "All tuners are currently busy" and the scheduler says "Recorder Off-line". Obviously I did something wrong, can anyone tell me what it was and how to fix it? Please!
