I guess the best way is just to show you. Here are 3 screen captures, 1250, 1281 and 1283. They're from a simple BD-25 with 2 languages, English and German. I un-check the German and with all version leading up to 1250 only the fold with the chosen language remains. After 1250 up to 1281 the empty language folder is still present in PowerDVD and my Oppo, it won't play in my Oppo even using the un-scaled original audio. Version 1283 changes the name of the folder and now it plays on the Oppo but not if I down scale a BD-50 to 25. Hope this helps.
