Thanks Mike. I suspect Jinx worked because you stopped recording 5 
minutes before the end. In my experience, stopping the recording early 
is a successful workaround, although of course it's a pain to tweak 
rules to do that, especially on programmes which are shown at different 
times of the day during the week (e.g. CSI:NY, which sometimes ends at 
1am on Five USA when the channel goes off-air).

For the other two shows, as I mentioned on 
http://www.gossamer-threads.com/lists/mythtv/users/464686#464686, I 
think the problem only occurs when a DVB-T slot gets immediately reused 
for another channel, which I know happens when Five USA, CBBC and 
CBeebies goes off-air, but may not happen on BBC4 and Film4, so it may 
be that those two particular shows weren't good candidates to 
demonstrate the problem.

If you, or any other UK DVB-T (Freeview) users, are willing to help test 
this tonight, good candidate test programmes would be:

CBBC - Jinx 18.35
CBeebies - CBeebies Bedtime Stories 18.50
Five USA - Cops In Crisis 00.45

To experience the problem, you should record, say, five minutes after 
the normal stop time. You should find that the recording is not playable.

Or if you have sufficient tuners, and if you can persuade Myth to do so 
(e.g. by adding a manual recording schedule), you could try recording 
the same program simultaneously twice, one stopping five minutes before 
the normal stop time, and one stopping five minutes after the normal 
stop time. You should find that the recording that stops early is 
playable, and the one that stops late is not.

Many thanks in advance.
