Ok. The recording ended early presumably when they finally cancelled the session because of the bad weather and the quali session following it recorded successfully. But the EPG did not change to show the filler programmes they put on instead? When I noticed the recording had stopped I risked looking at the MotoGP web site but it would have been more reassuring to have seen the EPG change.
(I was watching the Leeds United football match live which was why I was not watching FP3 live)
