Ben Hur, etc, Netflix, Blockbuster missing

[rlmbluray]

Why are not the great movies, Ben Hur, Ten Commandment, Sound Of Music, etc. not available from Netflix, or Blockbuster in Blu-ray.

Netflix told me the studio would not allow them to have these titles in Blu-ray.

That makes no sense to me.

Can anyone shed some light on this for me.

I was disappointed when I tried to order many of these titles and could only get them on DVD.

My only option is to buy them which I am not going to do.

Comments?

Thanks
