iDVD as a menu front end for AVI's?

I have a load of AVI's that come in just under 4 gig. I want to stick them all on a DVD so I can play them in my DVD player (my DVD player has DivX playback, so it'll play AVI's fine) I could just burn a datadisc, but thought it would be nice to have a DVD menu system.
After adding the fourth movie in iDVD (08) (out of about 20) it told me I was at my maximum of 80 minutes. It wants to re-encode everything to DVD. Is there a way to get it to do what I want? If not, is there any third party software that'll do this?
