there is also one solution i have tried.double click on file you want to change resume capability then go to its address. if address shows at end "start=0" then delete it till extension part.
ex
kxm5zio7jko4gmgd2czv3sgm/v.mp4?start=0
after delete
kxm5zio7jko4gmgd2czv3sgm/v.mp4
and press OK .
it change its resume ca[ability.
but it works sometimes.
