VLC remains the industry standard for playing almost any format, including VIDEO_TS folders.
A standard player sees a list of VOB files. Double-clicking VTS_01_1.VOB might play the first 10 minutes of the movie, but you will miss the menus, the copyright warnings, and the seamless transition to VTS_01_2.VOB . A true Video TS player reads the .IFO file first, allowing you to watch the DVD as intended—menus, special features, and all.
KMPlayer is a versatile player capable of handling heavy 4K and 8K TS files from digital broadcast sources.
KMPlayer offers a visually appealing interface combined with low CPU usage, making it an excellent option for older laptops and desktop computers.
