Blank Media BD 50gb Rewritable question

[THX-UltraII]

I own a Panasonic DMP-BDT310 Blu-Ray player which is Cinavia-free and at the moment I m burning my downloaded 3D .iso movies on BD recordable 50gb discs. These are quite expensive and because I only watch my movies one time mostly I was wondering if it is possible to burn a 3D .iso on a BD Rewritable 50gb and if this will play on my Panasonic Blu-Ray player. And IF this will work, how many times can you use a BD Rewritable 50gb if you handle it with care?

(ps. No diccussion please on why I m not using a Media Streamer Player or why I m not downloading 3D 25gb versions and burn them on a much cheaper 25GB Recordable. I have my reasons why I want to watch the full 50gb 3D Blu-Ray iso's on my standalone Blu-Ray Panasonic player).

Thanks for all input!
