So far as I am aware, none of the non-learning universal remotes yet have a built in code set for the DVP. Some of the OFA remotes can get a new device code over the phone. There is the JP1 route, too, but that has a learning curve to it.
You could order a box as a gift to someone for christmas and 'borrow' that remote to learn to a learning remote. Or you could find a friend with a Harmony and learn from that.
Edit: It does look like some remotes might have codes that work but YMMV.
It appears the URC UR5U-8700L has a Roku "media PC" code and is available for $20 shipped
here. No promises though.

I think it has been discontinued by URC. Their R7 for $40 at BB doesn't list a code.
But $500 for a remote seems a less good option than a new box!
