If I don't have the dvd anymore, can I still view videos that I had previously played?
I had a dvd. I viewed some videos on this dvd. No longer in possession of this dvd, can I recover those videos somehow?

No.
It makes complete sense that you could not recover this. Think about the copyright protections - if I borrowed ten DVDs from you (did not own them, and never paid for them), and watched them on my machine, should I be able to recover them and watch them again as if I owned them? Of course not.
