I'd consider my patch as a proof-of-concept rather than anything else. 
I'd be the first to agree that it could be done better but I wanted to 
minimise the changes.  I've been using this for a number of years and 
wouldn't do without it.  The "bookmark on start" means that playback 
almost always starts exactly at the start of the programme and the 
"extend until finished" means the end of a programme isn't lost if it 
overruns.

I did find a few problems with the EIT collection and I don't think all 
of them are fixed by my patch.  In some circumstances, particularly with 
channel changes, EIT collection stops.  That's obviously not an issue if 
it's just being used to populate the listing information but would need 
to be fixed for continuous running status.

The other issue with "extend until finished" that I never really 
addressed is that affects scheduling since there's always the 
possibility that the scheduler might have lined up a recording on 
another channel for that tuner.

Let me know if I can be of any help.  It would be lovely to be able to 
ditch my patch in favour of having it done properly in Myth.

David
