There is a limit on, i think, FAT32 drives (this means the way the drive is formatted), which prevented files from becoming over 2 GB in size. This used to be fine, but with DV it became a problem. From memory (i prepare to be corrected) some people such as Ulead found a way round it, to increase the limit to 4 GB. The limit is still there however.
This is what i suspect with your problem, and can be corrected by changing your drive from FAT32 to NTFS (under Windows 2000 and XP only). There are some issues to consider before doing this however.
Let me know if this is indeed your problem.
