Questions about the 1100 models (including hacking)

Has anyone noticed the “jerky movement” problem on these when using the 3, 4, or 6 hour setting (as can happen with the 5000’s)?

Also, while I know there’s the region hack using the remote control, has anyone come up with a hack to take care of macro on the 1100’s? Any Mr. Wizard stuff out there?

Does anyone know if such hacks might also work with the re-named ones being sold at Radio Shack? (Obviously LiteOn machines, but under a different name.)
