The TV programmes you mention-Twilight Zone etc were originally made on cine film and are therefore completely independent of any television standard. however they were obviously converted to something for DVD.
Why not make your own DVD?
Convert the VOBs on the offending DVD to MPEG2 using this simple and very good converter (free)

Once you have the MPEG2 convert back to appropriate DVD standard with something like Windows DVD Maker (free)
