Playing TS and M2TS Blu-ray files

TS, M2TS and MTS can contain broadcast, disc or camera video; AIX opens supported streams directly.

Where these files come from

TS stands for transport stream — the format broadcast television and Blu-ray discs use internally. Copying the video without re-encoding preserves the encoded source picture; the container and file size can vary.

Why they are awkward

Transport streams can need probing for seeking and duration; playback depends on the actual streams, file and PC.

Opening them properly

AIX opens supported TS, M2TS and MTS streams and lists the chapters and tracks actually present. Supported graphics hardware can accelerate decoding; playback depends on the file, driver, storage and display.

Why the file is so large

A stream copied without re-encoding retains its encoded video; size depends on duration and bitrate. That is the point of keeping them: no generation of quality has been lost. If playback stutters, check decoding, storage and the source file.

Chapters and tracks, when the file contains them

A standalone TS or M2TS file contains only its own streams and metadata; select the audio, subtitles and chapters that AIX lists for that file. All of them are listed and switchable while the film plays.

Playing them from an external drive

Most people keep disc rips on an external disk rather than filling their PC. That works, and there is nothing to copy across first — but a slow or old drive can struggle to feed a high-bitrate file fast enough, which shows as brief freezes rather than steady stutter. Compare playback of a local copy to help test the storage path.
