Slight O/T - File sizes for PC?

Hi guys,

Thanks for all your help re: Digital 8 question.

My next problem is that I burnt data DVDs for my client, some up to 4.2 gig in size. They were native .DV files, and I can't recall having had this problem in the past.

He can open the smaller (less than 1 gig) files, but the others are coming up in Quicktime saying 'not valid movie files'.

I know this is a FCP forum, but its related, so any of you who are both mac and PC friendly have any tips for me out there?

I've done the usual google/lafcpug search to no avail.

Justin.
