There are a number of scaling DVD players available with outputs beyond 480p, with the Momitsu V880 being most popular.
It will output any resolution you want. If you need 864p to keep the scan lines touching on your CRT projector it will do it.
You're never going to have the detail in an HD source, although decent DVD transfers can still look very good at 1.3 - 1.5 screen widths.
