PCR SMEARING

We have been getting a lot of smearing in our PCR reactions.  Sometimes we
get a discreet band, but most of the time its a smear.  We get this with
different primer pairs so it dosent't appear to be confined to one pair.
The reactions are all set up on ice to minimize aberrant priming before
thermalcycling.  I would be grateful if anyone could give me information on
how to eliminate the problem.
