2 Gig limit on files?

I have just recently started playing around with my video camera and linux. I am using Suse 9 and Main-actor from my 8.2 cds as I cant seem to do anything with the ver that came with 9. My problem is I am trying to export from Main actor approx a 6 gig file in DV1 format so i can then use kino to make a svcd of the video file as Main actor only will make a vcd. However the problem I am having is that when exporting the DV1 file from Main actor it crashes when the exported file gets larger than 2 Gig. I thought this 2 Gig limit was no longer a problem with Linux? Does any one know how or what I can do. Cheers, Glenn
