With a bluray disc they offer 25GB for single layer & 50GB for dual layer rewritable disks for recording.
Do you do a lot of recording to DVD as it is? Do you plan to?
I don't really see the use of DVD/BR recorders to be honest - why not just get a decent PVR?
Bluray is high definition,whereas DVD....aint!!
I will answer as if this is a serious question:
It seems you want to watch BD on something other than your PC. Buy a BD player if you have a HDTV and want to watch HD films. You have a DVD recorder already (which is what you're classing as a standard player), so you don't need another standard player.
Are you actually recording?
