Seems unlikely but http://code.mythtv.org/trac/ticket/10833 might be of  
interest regarding UK radio/ringbuffer issues. 0.26/fixes does/did have  
some ringbuffer optimisations that don't work well with UK radio because  
the detected stream rate isn't correct.

IIRC I had no problem with recording - those issues showed up on playback  
only. However YMMV or recent backports may have exacerbated the problem -  
I haven't updated for a while.
