Don't think movie maker works on windows 10 for some reason. I think you might be on to something with the DVD, not sure why but the first movie I burned worked find and played number of times. tried to play it yesterday and it wouldn't work. (cant play this DVD) came up on the player...
I have several kids movies on my laptop. I want to burn them on to a DVD-RW so the lads can watch them when ever and I don't need to collect the laptop to the TV. I burned a Movie to a DVD and it worked fine but none of the next movies will work. Then burn on the DVD but wont play on my DVD...
