He's not really suggesting conversion per say, just playing the DVD content straight from the DVD media like any other DVD player does. That does assume some kind of conversion in itself but should fall under fair use. It would be impossible to watch a DVD at all otherwise. It gets into the realm of the legality of using Linux to watch a DVD, which is generally considered illegal, but looking around the net there seems that there may be some legal precedence that says otherwise. If Apple somehow left their DVD player decryption code in iOS on the aforementioned iPad, for which they presumably do have a license to use, then there should be no legal qualms at all.
