an MP-4 movie files have been downloaded from different sites using " videodownload helper " ( FIREFOX app ) with no problems ever. Videos can be viewed on computer or DVD copies can be made....NO DRM , I assume !!!
However, when placed onto " movie maker " , preview screen is black !!!!
Everything is up-to-date ...personal homemade MP4's work in preview...
I have read that DRM videos cannot be copied , but I have downloaded them and copied them ????? to DVD's , my Kindles.....
thxs
