Blu-ray burning blues

Even though Encore (windows pc) says it successfully creates a Blu-ray disc, trying to play it on a Samsung BD-P1400 generates a "unable to read disc" message. After reading everything I can find, and upgrading software, etc., I still can only make coasters. Encore says the project has no errors.
I even created a blu-ray image from Encore and burned a disc using ImgBurn and got the same result - no play.
The project is a small test. One menu, one button, one 1 minute mpeg2 720p 59.94 timeline.
The video was created in FCS 2, mpeg2 created in Apple Compressor using the HD MPEG 2 30 minute setting and changing the Stream Usage setting to Blu-ray. Encore on windows seems to like the files - importing and previewing with no problems. It also doesn't need to transcode the files for blu-ray. Author and Build the Blu-ray - Encore thinks it is successful. Still no play. I also know of no way to look at what is on the disc! Please help!



Encore CS3 3.0.1.008
Dell Precision 360 3Ghz Pentium, 2GB ram
Pioneer BDR-202 internal burner

Plenty of disappointment and frustration.
