Help...I'm using Premiere on a MAC

Hi,

I am using Premiere 6.5 (yes, I know that there is a forum for that...but nobody appears to know the answer to my problem). I have access to a range of new MACs( G4, iMac etc.) However, currently I am trying to make a movie on an iMac. I have a really good quality movie made by Premiere and it has been exported as a DV. But it is huge and I need to know how to compress it on my MAC to a size that will atleast fit on a DVD. the file is 6.5 GB!

Does anyone know what kind of plug in I need to buy to make this work? I understand that MPEG is the files that most people use when exporting DVDs. However, the Premiere version that I have doesn't allow for MPEG exporting when using a MAC.

Thanks for any help!
