Wait a minute. I agree that re-encoding is not necessary if LG is simply changing containers, but if he has changed the frame rate from 24 to 23.976 fps, surely it is necessary.

I wasn't suggesting he change the frame rate - the Samsung (and VLC) is picking up the wrong framerate, somehow, from the .m2ts. I'm hoping RipBot will return the wrongly set 48fps .m2ts to a 24fps .mkv, the same way it reset my 47.952fps .m2ts to a 23.976fps .mkv.

Whether or not the TV will actually play a 24fps .mkv is another matter, but I'd think it would.
