Why do DVDs use TS files? Apologies if this isn't the right community for this question, but I'm wondering why TS files are used for DVDs and not a more widely used format like MP4s or something
DVD makes use of the Program Stream(PS) container whereas Terrestrial Stream(TS) uses for unpredictable transmission.
PS mostly uses MPEG-2 codec whereas the MP4 uses better video encoding scheme likes 264, 265 or MPEG-4.
