Dear friends, There are a lot of movie files running on internet. Some of them have been created with special options and diferent spects so i think it is impossible Zidoo team can test ALL of our files. But, there is a standard repository with major type of movies. Here it is http://kodi.wiki/view/Samples I think zidoo team have to TEST all this samples and have to garantee the perfect sound and video on this files. Other files could be "cause study" Users, all of us, should do the same... First of all we have to test the files from repository (test from usb, from samba, Fast forward, Jump specific point, pause, change audio, subtitles, etc...) and second if our especific movie do not work post on "cause for study movies" section all the file information. Do you agree? There is a special 3D and UHDTV 4k repository here: http://demo-uhd3d.com/
