"DATA DISC" - What's going on?

[Asterra]

As some may suspect, I'm trying to burn a certain small movie (just a menu, really, so I can test the menu without having to waste a precious BD-R) onto a DVDR and play it on a PS3. Imgburn recognizes what I'm trying to do and makes the appropriate adjustments. UDF, whatever.

But the PS3 never autoplays the disc. It recognizes it as a "data disc" and lets me navigate the contents... Not very useful if you're trying to test a menu.

Made three separate burns, trying to mix it up. Tried building an ISO created by ImgBurn. Tried burning directly from the BDMV folder. Tried burning an ISO created by Encore. Same results every time. "Data disc." Never mind wasting BD-Rs - the cost of DVDRs is starting to get irritating.

Anyone know what I should be telling ImgBurn in order to get this to work?
