Vista Premium - Movie Maker, DVD Maker - problems!

I'm experiencing problems with Movie Maker (and DVD) maker in Vista Premium.

I've recently upgraded from XP (on a new machine) - I've been using Movie

Maker on XP for ages.

My main problems with this version are:

I can only add transitions in Storyboard view (in timeline view wmm closes)

I cannot expand the Video Track to mute audio (again the programme closes)

I cannot save as an AVI file (again programme closes down) I can only save

best fit for my computer

I cannot publish directly to DVD (DVD maker will also not work with AVI

files - it closes down!)

Does anyone have any suggestions? If so, I'd be grateful - I'm finding it

frustrating that I cannot produce the quality of video (and editing) I've

been used to with XP.

Thanks
