3D stretch for Java authored disc

You may already know this, but 2D is another option. It's only the Java+3D combination that's a problem for the 93. Java+2D zooms fine, FWIW.

You didn't answer his question.

A cheaper option would be the HTPC direction, which can be had in either built or premade. Decent pre-builts should have all the features of a normal 3D blu ray player including the Oppo, as well as working as a scaler. I would look into the HTPC section if you want to make a build. It's worth noting there are not many freeware software that works properly with blu rays, so take note. But you should be able to have a cheaper machine than the Lumagen Mini 3D.
