Hi welcome to our forum.

This is a frequently misunderstood subject. Firstly .TS short for transport stream, is not a file format at all. It’s a container that combines different file formats like video compression codecs (eg H264/AVC. mpeg2) and audio compression codecs (eg mpeg 1 layer 2, Dolby Digital, AAC etc).

Each container has the capability to contain various different video, audio and subtitle formats.

If the kit you are playing back to doesn’t recognise the container (unusual these days for transport stream) and has the capability to decode the actual contents then in some case simply changing the .ts to say .mp4 might work.

Not familiar with your specific box but our UK boxes .ts aren’t in fact .ts files at all but in a slightly different container format .m2ts.

Changing the container doesn’t affect the quality at all provided the actual contents are not recoded.

DVD’s in the UK use mpeg2 video compression 720 x 576 25 fps and DD or PCM audio. They use a slightly different .mpg (programme stream) container, often changing the extension from .ts to .mpg will make them work.

If you still need software

Check out TSmuxer.gui and Handbrake.

Here is the text with the information.

That looks absolutely normal. With what and how are you trying to play back the file ? Most media player software on a PC should be happy (eg VLC) or it could be burnt to a DVD blank in DVD-Video format using DVD authoring software (eg DVDFlick).
