I just bought a Canon SX510 "combo" camera for stills and HiDef video
It uses a MOV wrapper, but I didn't have to install Quicktime on my Windows computer with CS5
I did a quick test, exporting from PPro with a BluRay setting... authored in Encore and wrote to a BDMV (and CERTIFICATE) folder
I used Imgburn http://forums.adobe.com/thread/1322583 to write the folders to DVD... which plays in my Sony BluRay player
Not something I will do very often (my relatives don't have BluRay players for my home video) but now I do have the option
