I have used movie maker when my grandchildren have visited and other projects.  When I was on 7 there were no problems playing the DVD on the TV.  Now that I have upgraded to Windows 10 the movie will only play on the computer, no matter what I cannot get it to play on the TV. I am attending my daughters wedding in September and would like to make a movie from the pictures so she may watch it on her TV.  PLEASE HELP.... I have read something to do with file extension but that is beyond my knowledge, as an added note I am using the same brand of DVDs I used in the past.
