Stupid 1633 question, forgive my ignorance

I’ve got a 1633 flashed to 1653. Can I use 8 gig DVD disks in it to copy more data on one disk?

You should already be able to use 8 gig DVD disks with a 1633.
You can also cross flashed 1633 to 1653 if you like but it will void warranty.

Thanks for responses/info
