[mythtv-users] Migrating from UK EIT to XMLTV guide ?

[Roger Siddons]

Is it possible to migrate from the EIT (UK OTA Freeview) to Radio Times  
XMLTV whilst retaining my recording history ?

I've been on EIT for many years but I was considering a change to XMLTV to  
obtain better season/episode data. However I notice that the RT program  
ids seem to bear no relation to the EIT crids. Thus Myth is going to  
re-record everything I've already watched and I don't fancy managing it  
all manually.

I haven't yet worked out how the RT program ids are allocated (I assumed  
they would be the based on the crid from the broadcaster). Can anyone  
point me in the right direction ? More pertinently, is there any way to  
convert between them and the crids ?

I've seen lots of discussion about the pros/cons of EIT/XMLTV over the  
years but hadn't appreciated that, having made a choice, I was stuck with  
it!

I think the only alternative is to delete all the crids in my database so  
that Myth is forced to use subtitle matching. But I'm sceptical that will  
be satisfactory as many of my programs have no subtitle (eg. Grand  
Designs) and I know the descriptions aren't going to match.

Someone must have tried this before. Any advice or experience to relate ?
