ATI video cards do not like projectors at all! Especially the ones in laptop computers. When a projector is connected up to an ATI card, they seem to ignore it's prescence, sometimes disabling the Function key button sequence that enables the rear monitor port...other times, the ATI's "plug and play" system goes haywire and sends the projector some screwball resolution that the projector won't run.
On ipods... I've got an ipod shufflle. That thing is amazing. So tiny, yet it can store so much, and sound good. Great to use while exercising. The best thing is that you can drop one, and it doesn't damage it!
