Network Home Directory’s and New iMovie 7.1 from iLife 08

Hi All I am having problems with the new version of iMovie and network home directory's . The new app wants to write to the local drive iMovie folder even though a network user is logged in. It will not give you a choice. It wants to create the Movie Events folder locally, and we don't let them write to the local hard drive. Have tried going into the iMovie package and looking for a plist file with a path... but am not having any look. We recently upgraded from 60 emacs to 60 iMacs with this new version on... needless to say the old one worked fine!!..... Hmmm Any help/advice please.... we have lots of different users on these machines, and I don't want to open them up.. to start saving locally... Thanks Nicola Clarke
