Fortunately that's not ALL 1200's, only the BD-01200 which I suppose was the original 1200.
Mine is the BD-P1200, and it plays every BD I can throw at it.
Second shoe drops....
I updated the firmware in my BD-P1200 for this, and now analog 5.1 doesn't seem to work correctly.
Hmmm...... I should have stayed with the previous firmware.
That sucks. Anyway to remove the firmware?
