Upgraded a dual processor 1ghz machine with leopard. everything works great except the Idvd ! I have tried installing the upgrades idvd 7.01 and 6.5 which apples support site say will work. I get an error the drives are incompatible, or cannot not be used. Whats with the drives? I cleared out erased the old files from system 9. Now it says it can't find the base application. I will try re-installing Idvd I have a disk for Idvd professional that went to system 9 or early 10 version. It all worked in Panther.
