I've enclosed samples from a few of the scripts that have been successfully used for fMRI studies here.  These were all used for event-related fMRI studies.  I only included a handful of trials from each to save space.  My experience with DMDX has been that a little inital trial & error is all that is needed to get your timing right.  One common mistake, is that if you are programming on a different computer than will be used at the scanner, be sure that the two computers have the same refresh rate.  (or at least be sure to program your experiment to run at the refresh rate of the computer used at the scanner.)  Feel free to email me if you have any questions, or troubles opening the attachments.
