I've long since wondered about some recordings that seem to indicate they have the right length through thr GBPVR interface, but when watched actually play for an hour and a half and then stop.

The recording time in Recordings doesn't match the play time in the seek bar - often by hours.

Last night I recorded a 3 hour show during the middle of the night to test this out (one of those stupid quiz shows that go on forever that nobody watches).

8/08/2006 12:00:02 AM.690 VERBOSE [5] recording started
8/08/2006 12:00:02 AM.690 VERBOSE [5] Programme is now recording

... (3 hours later it finished recording) ...

8/08/2006 3:00:00 AM.066 VERBOSE [5] Recording has passed endtime+padding. Stopping.

... (and then a bit later processing kicks in) ...

... (and a couple of hours later, that's done) ...

...

After 3 hours transcoding kicked in for the program as normal, and this morning as I skip through the file, I notice that it is 1 hour 27 minues long, not 3 hours. Transcoding has killed the file. What can I do - other than turning off transcoding altogether?

This has been discussed a few times in the past. I cant remember the exact details, but the forum search should turn up some info for you.

aah, I take it you mean this post:

Looks like it's a ffmpeg problem that people scratched their heads over and then found other solutions that don't involve ffmpeg. But no word on the actual cause :-(

I tried replacing ffmpeg with a newer build (ffmpeg CVS 2006-07-03 rev: 5570), but the next time I opened config, the MSI installer thingie came back up and overwrote my changes again. Any way to stop that bloody thing from happening?
