Samsung proved that by newer firmware that removed encoding that worked but was not in the documentation.
The thoughts I've heard of suggest this was to make room for other fixes.
My conclusion: Folk want TVs to be on par with PCs in web and video playback.

SOLUTION: change format to .mkv
Movies play just fine on computer. I had more than 30 such movies.
Extensive testing led me to:
Redownloading and recompiling
Recompile movies multiple times.
Compiling in temporary formats such as .avi (my TV wont play avi) and then converting to .mp4 for the TV using an independant converter.
Compiling video in parts to avi and then recompiling the parts into one movie
Compiling in smaller file size formats
NONE of the above (and more) methods would allow the movie to play through to end. The best result I could attain in these efforts was to have the movie stop at a different time in the movie.
CHARACTERISTICS of problem:
NOT related to file size however it appears to happen mostly in files over 2 GB
NOT related to Time length of movie however it appears to happen to those over 2 hours in length
NOT related to any piracy protection conspiracy. The TIME (in hours:minutes) and byte point of the interruption is not the same in all movies which shows it has nothing whatsoever to do with a hidden agendy of piracy protection by the manufacturer. If it were the manufacturers using a piracy protection they would not wait until near end of a very long movie and they certainly would put such protection into .MKV also, which they have not done.
CONCLUSION:
Multiple brands of TVs are having this problem (not surprising they all probably use the same codec chip). The problem seems to be the .mp4 codec they are using and possibly the size of video chunk running thru the codec interpreter at a given moment. If you fast forward thru the video you will notice the movie doesn't end suddenly, it just goes black and sits there for a time as though it is unable to interpret the information (unable to calculate).
MP4 microchip is something they made millions of and they buy them by the millions. Simply bad engineering and poor testing.
SOLUTION:
MKV has the same resolution and quality as MP4 or other MPEG copyrighted codecs.It also has the same file size. MKV is an open and free format used primarily for DVD. Its codec in these TVs seems to be solid circuitry.
MP4 is not free and it seems the codec (circuitry) on these TVs is faulty.
