I have set this setting to 1500 (25 minutes) because tv stations around here are notorious for not sticking to schedules.

Sometimes, annoyingly often, it fails to record the extra 25 minutes, and I wonder if it isn't handling my 2 tuners correctly.

Example

I had two shows set to record, both starting at 7:30, one was 30 minutes long on channel 7, the other 60 minutes long on channel 10. Then a 3rd show was due to start at 8:30 on channel 7, i.e. on the same channel as the 30 minute show.

What it did was record the 30 minute show from channel 7, with 25 minute overrun, i.e. 55 minutes total, and it recorded the 60 minute show from 10, but without the 25 minutes overrun. It did also recorded the show on 7 that started at 8:30.

Obviously, it could have recorded the 25 minute overrun on the show on channel 10, as it was recording on the second tuner which had nothing to record (for many hours to come), but it didn't.

It's a pity this global setting is unreliable, because it means, I have to remember to manually set an "end late" time on all shows individually that I really really don't want to miss the end of, especially those that habitually end a bit late.

Can't help you with your problem but thought I'd chime in that my setting for this does not work at all. Both my record before and after global settings didn't work for 2-3 years but I finally fixed the before setting last month by correcting the hostname parameter manually in the mysql settings table. But the record after setting still doesn't work. Not as important to me as the record before setting, but sure wish it would work.

I have found it more reliable to set the time extension manually for each schedule. As I usually only have to set the schedule up once per series it isn't a big hassle and I can take into account the reliability of the network and the timeslot.

I think you have a valid point, I will start doing it this way.

Although, there is a rather unfortunate downside. That is that the time extension, when set via the "end late" option individually, is mandatory - therefore if a show starts immediately following the one with the extension, it will not get recorded (unless a second tuner is free).

Logically, the coders could pick this up in the scheduler, and "cascade" the time extensions when shows are consecutive, but I doubt they have done this, as I tried extending the time on the first of 2 consecutive shows last night, and it descheduled the 2nd one, to allow the first one to be extended.

What should have happened is that the 2nd show should have "started late" by the amount that the first one was set to "end late" and to "end late" by the same amount, thus shuffling everything along by that amount. This can be logicall extended to any number of consecutively scheduled shows, taking each one's "end late" times into account.

Maybe a developer will see this as a suggestion for an improvement to the code.

Other than Nigel, I'm aware of no other MythTV dev that frequents the forum. If you have a bug or feature request/suggest, you need to visit mythtv.org (svn and wiki).

Thanks for the tip Cecil.

There is a plan already for allowing mythtv to multiplex more than one recording at a time from one tuner. This is to allow overlapping recordings from one channel, so you would be able to record TopGear+10mins and the following Southpark from SBS from the one tuner. It is also hoped that this feature will allow you different DVB subchannels that are on the same frequency, like "ABC TV" and "ABC2" or "SBS" and "SBS News".

This will help, because it means a conflict is less likely to occur. Very interesting - I'd be interested in reading how it manages to multiplex between 2 different frequencies.

Of course, it doesn't change how it mishandles the situation when it decides to not record the overrun, even though a tuner is free, which is what my example in the first post illustrates. The behaviour is as if it sees that a show is scheduled for 8:30, and so it allows the overrun on the first tuner that finishes it's recording at 8:00, but cancels the overrun on the second tuner that is finishing is recording at 8:30 - even though there is no logical reason it could not have continued recording on the second tuner, while the 8:30 show started recording on the first tuner.

I believe its recording from the same mux, rather from separate muxes.
