[mythtv] Watch Recordings Screen wierdness

[Stuart Morgan]

I've noticed in the last week some very strange behaviour in the Watch 
Recordings screen using current SVN.

I have it arranged by category and whilst scrolling down the programmes in the 
'film' category it suddenly 'jumped' to the first programme in the 'Leisure & 
Hobbies' category. I can't reproduce this consistently but it happens most 
times I'm browsing the list.

I've seen similar but not exactly the same behaviour on my other myth box. In 
this case when exiting the 'Edit Recording Schedule' for a particular 
recording, it jumps as before to a different recording in another category. 
Both were built from 8763 and I ran make clean & make distclean beforehand.

I've searched through the changes made to plabackbox but can't see anything 
obvious myself. I'm just checking here before opening a ticket.
