Thank you everyone who has commented. I have got to the bottom of the 
problem. The disk on the 0.25 source system is "past it best". As a 
consequence some of the database turned out to be a mess. I have managed 
to recover enough data to restore the recorded programmes from the 
source system. In effect I've done a partial restore as described in the 
mythconverg_restore details on the web site.

Thanks :-) Ken
