I'm totally confused--I follow instructions carefully--and can't add stills to my idvd buttons. I select the button, drag the photo from iphoto and can't get the green plus sign. Twice in 4 hours of messing around, I got one to stick, but that's all. I'm dragging from iphoto. The program is 1 hour long and has 19 chapters. This is a brand new computer 2.8 ghz, intel core, brand new software. Anyone ever seen this problem? I would appreciate any help Thanks!
