Is it possible to create a DVD-VR data disc?

the reason I ask is that I own a funai hd-b2785 DVD/HDD Recorder with a 250gb hard drive that I never use.

the only way it appears that I can get anything off a physical disk onto the hard drive is if the disk is in VR mode.

in a perfect world, i’d want to archive a few films (if not all of them) onto the hard drive, but as yet, i’ve been unable to work out if it’s even possible to create a VR data disk - but even then, it’s no guarantee it’ll work.

in another perfect world, i could re-flash the operating system of my DVD recorder so I could put whatever i wanted on the hard drive …

any clues or help most greatly appreciated - cheers
