Try another tool to create the MPEG. IDL isn't the best tool in my
experience. I don't know if it is the choice of encoder or what but I have
had consistently better results using other tools, even with the new options
included in 5.4.
You didn't mention your platform. On windows, I use VideoMach
(http://www.gromada.com/) which is a shareware program ($19 non-commercial)
which will allow you to change the playback rate and set the quality amongst
other things.
I'm sure there are command line tools for Unix which may yield better
results. It may be worth a search.
