Cancellation of delayed playback with station "close"

Let's suppose I had a PBS America show on pause, to watch what's left of Newsnight, and then I return to play the documentary. Despite ad-skipping the doc is still playing from the disk at midnight when PBS America changes into a pumpkindata service. At that point the playback is cancelled in favour of the completely uninteresting "Back at 13:00" that the channel shows for 13 hours of the day. No doubt the unwatched material is still in the TSR buffer and perhaps could be extracted by nicesplice (in another place). But why, and is there anything to be done (apart from actually recording the show, or having watched it on BBC when it was first shown, or on BBC4 if it comes around again)?
 
Yes, I've been caught up with that sort of thing. I have a mental note to actually record rather than rely on timeshift (especially because I have a habit of accidentally changing channel).
 
I always set record for ALL the programmes we want to watch (unless it would create a recording conflict) even if we are likely to watch it live.
It provides a handy highlight in the epg and provides protection if we are interrupted by phone calls etc during the show.
 
The original question was somewhat on the lines of 'how can I get to 2029, say, without waiting for it?', hence '... apart from ...'.

To analyse further, from the UX viewpoint it seems weird that the delayed playback depends on the current transmission state of the logical channel: the user just sees (eg, PBS America) transmitting the whole time. But maybe it's possible for the conceptual channel associated with a LCN to change across a service change: presumably at least if the conceptual channel associated with a LCN changes with a channel update. And then maybe detecting that was too hard (on a scale of "didn't understand the problem" through "couldn't be bothered" to "can't be done")?
 
It might be something that can be fixed now. What happens if you let, say, Claude take a look at the Humax binary – would it produce decompiled code, and a commentary?

It doesn't. Presumably it's something to do with the elemental PIDs transmitted that upsets it, but we won't know that until midnight pumpkin time.
Here's what the service currently contains:
Code: 
PMT PID 1019
Service 27968 PCR 2701
PID 2701 Video MPEG-2
PID 2702 Audio MPEG-1
PID 2703 Private MPEG-2 Packet
PID 3806 Private MPEG-2 Tabled
The video/audio are self-explanatory. The next two are subtitles and MHP Application Information Table (which effectively contains just a link to a web-site - in case you are interested it's "http://cf.3-t.uk/tvc/tv/redirector/index1.html?ic=654" and you can read the JS it serves up and work from there).
 
And the answer is:
Code: 
Service 27968 PCR 8191
PID 3806 Private MPEG-2 Tabled
PID 4006 DSM-CC U-N
So V+A+S go completely and some DSM-CC stuff comes in.

DSM-CC

So it looks like the Humax blob gets a signal that AV is gone and that causes it to reset any activity associated with the channel.
