Digially stored NTSC files and playback?

[targeteye]

He all i'm looking for an education. I want to playback old tv shows in my two Sony portable Trinitrons. I would like to use something like an old WD TV with stored files , output on its composite output and then thru a Modulator.

Is this doable and is anyone doing something like this?

barring that I suppose i could just buy the DVD's in ntsc format and use and old dvd player but i'd rather have the programming stored on a hard drive.
