Can't speak for Blu-ray, but with DVD, it is very important that the disc be burned as "DVD Video". For instance in Windows, if you simply drag the VIDEO_TS folder to a blank disc and burn as "Data", it is not going to play in most DVD players.
A computer will usually recognize the content of the disc as being DVD material and will likely play it. But DVD players are expecting a disc formatted a certain way, which a data disc is NOT, and therefore will not play the "data" disc.
A lot of the newer DVD players will play more types of media, such as MP3 and stuff, so possibly more of them would now recognize a VIDEO_TS folder on a data disc, but to do it right, you must burn as a DVD Video.
Most disc burning software will offer options of "DATA" or "DVD VIDEO" because there IS a difference in track layout, and there is special info written to disc that identifies it as a "DVD" also.
In the case of creating a Disc Image, or .iso file, from Encore, then that is a "snapshot" of the DVD with all the right stuff in place, so any software that can use an .iso will make a proper DVD. But again, you cannot just burn the .iso file straight to a disc as data, the software must be capable of creating a disc from an Image.
Hope this makes sense
