I wrote a 4.2gb file to a dvd, I think with nero 6 using iso9660, I tested it after I wrote it and it was fine. Now a few months later I have come back to use it and when I put it in the dvd writer driver it just says it is only 224mb long and I need the whole file to be able to access it.

Iso buster says that there is 4.2gb of data written to the disc, in 1 track and 1 session, but it also lists the file as 224mb.

Does anyone know what caused this or how I get out of this predicament? I have attempted to extract the data raw with isobuster, I found the begining of the file at lba 25, but I don't know where the end is as I don't know much about the lead in and lead out of the discs, does anyone know if there is a set amount of leadout, as it would take forever to guess it, anyway I hope someone can shed some light on this problem for me, thanks

If this was a Multisession disk, created in Nero, then you will only be able to read the file, on a PC that has Nero installed ..... could this be your problem ?
