A DVD player has no record function either, so the answer is - there will be a software based encoding application that complements the player.
Apologies for pursuing this. What I'm asking is, where or how will the DVDs be recorded when using REDRAY for playback? My understanding was that it will be possible to playback a two hour movie in 4K, but I don't understand where or how the dual layered DVD gets recorded in the first place?
edit: never mind... I re-read your post and it is now clear. Sorry
