New at burning

you should set the target device to "iso disk image" in dvd shrink, then burn the iso with dvd decrypter.
also your Hard disk format must be NTFS not FAT32 otherwise you get error for iso larger than 4GB.
if you don't want re author the movie again with your pentium 2, get clonedvd from here and choose 3rd option and browse to those IFO/VOB files, then burn them.
