This was foremost in my mind, and Evan has shown what were my suspicions all along: a tablesaw is not the best tool for the job.
If you have access, a great tool for this application is a bandsaw with a fairly fine-toothed blade. Alternatively, try a jigsaw but make sure you have the workpiece's cut line very close to a solid surface. The better-quality jigsaws (like Bosch or Milwaukee) will do a better job because of the smoothness of the oscillating mechanism in the saw.
