just noticed entries in my log file which i don't like:

2008-07-26 02:28:02.426 DB Error (change_program):
Query was:
UPDATE program SET starttime = ?,     endtime   = ? WHERE chanid    = ? 
AND       starttime
 = ?
Driver error was [2/1062]:
QMYSQL3: Unable to execute statement
Database error was:
Duplicate entry '55101-2008-07-28 22:00:00-0' for key 1

anyone know what they mean and how i fix it?
it may explain my channel changing problems
