I think this is certainly a real issue with a lot of grabbers 
(tv_grab_uk_rt for example).  The current code tries to delete all the 
entries for a *given* day, then runs the grabber to get the new data.  
Obviously if the grabber is returning too much data then it will cause 
insert errors.  I guess that there are various workarounds like doing a 
more selective delete before every insert, but it might be easier to 
just examine the data coming back from the grabber and mask off anything 
for the wrong day (actually will have to check, but I thought there was 
already code in CVS to do this?)
