Not sure what you're saying here.
Duplicate matching will work if they both supply the same category, title,  
season & episode. And the ultimate source for both is the Press  
Association so generally it should work. Apart from the fix-ups....

The EIT program numbers are completely different so your radio recording  
history will effectively be reset. Atlas supplies season, episode, total  
episodes for most programmes but there are still a few R4 series that are  
totally unmarked - "More or Less" is one example I noticed.

0.28 now picks up episode & total episodes from EIT (it provides seasons  
for very few programmes and not for any R4 radio that I've noticed). So  
you may prefer to stick with EIT for radio.

Atlas uses a form of line-ups so you should find it uses your correct  
region automatically.

Is this because ITVBe isn't in the supplemental mappings ? I thought they  
were just a snapshot packaged with the grabber, so won't have the mapping  
for any new channels. I assumed this was to satisy the XMLTV spec. You  
could try adding a user mapping.
