Q:

file exceeds the file system size limitation

I have an ~4.5GB file and am trying to burn it onto a DVD using power2go software on Win7 PC. 
When I trigger it to start burning, it stops with the following message:
file exceeds the file system size limitation

I've searched for the solution on this site (not found) and on the web: found some references to FAT32 limitation and the proposed fix is to switch to NTFS.  But this hard drive is already NTFS. 
Please help if you [may] know what the problem's cause is.  Thank you! 

A:

By default a DVD uses the ISO 9660 file-system to store files.   This file-system stores file sizes as a 32-bit integer and as such has an inherit limit on file sizes being limited to about 232 bytes or ~4GB.   There is an extension to the ISO 9660 spec that works around that limitation, however I'm guessing the software you're using doesn't support that extension.   Perhaps try recording with Infrarecorder, which supports the extension.
