[FFmpeg-user] MTS to MP4 lossless conversion issues

Definitely upgrade. I have no issues with aac on my version of ffmpeg. I
believe the latest for Windows is 3.3.2. I'm on Win 10 but that shouldn't
be a factor in running aac with the latest version of ffmpeg. Win 7 should
behave the same way.

Keep your old version of ffmpeg just in case. :-)

Cheers.
