Ok, update. MX player WILL play them. But my DVR breaks shows up into 20 minute files. Fox.mts, Fox.Mrs.,Fox.Mrs. Etc. If I use a video player it only sees the first "chapter"and only the first. Using a file browser, I can see and play all the"chapters" . Any suggestions on how to get the player to pay the entire file, instead of stopping at the end of each chapter and going back to the file browser?
