I am still frustrated by the limited support that Apple gets from hardware manufactures but also the limited support Apple has in their OS for existing and well known hardware. I consider Memorex a pretty well known brand so asking for their DVD DL burner to be picked up shouldn't be to much to ask for, but apparently it is. Ugh, now I am going to have to pick up a unit that cost $100 more and does the same functions in the same form factor. Does that make any sense? Yeah, I didn't think so either. Such is life I suppose.
