I have a windows XP professional system with NTSF formated drives.
Sprtnbit just verified that his Windows 7 machine also produces this error.
The problem isn't creating and writing the file, because getFLV can sucessfully write a 4 GByte file (It just erases it after the file download completes). It appears to be an internal problem with your program, where one of your variables has a 2048M limit. It is producing a calculation error when the size becomes greater than 2048MB.
