[mythtvnz] Some recordings refuse to be deleted

[Paulgir]

Hi Folks

I was tidying up the storage drive by using the "delete forever" function  
to remove unwanted recordings.
This was generally successful except in the case of 8 of the earliest  
recordings which were made soon after
I got my HTPC running.
 From the deleted recordings view the "delete forever" option removes the  
selected recording but they reappear
on the list within a few seconds.
I have checked that the recordings are not marked "preserve" and they can  
be played from the list.I have tried
to undelete and delete again.So far nothing seems to work.
The recordings are all from 3 dates:  2 from 27/1/12;1 from 33/1/12 and 5  
 from 1/2/12.
Any ideas how to remove these?
