Netflix and Vevo display problems

Hello friends, i have just bough a firetv2 and i am having some problems with Neflix (displays with a lot of artifacts) and vevo (does not display at all). See attached images for clarity on my problem. the rest of the apps i have tried so far work well. and in the case of netflix, once i pick a stream, it displays as it should, the problem is in the menu section
I'm on 5.0.5.1 with updates disabled and not rooted. i will root when i get a cable, and then i will install TWRP and the latest prerooted rom

any idea on what i could try? i already deinstalled netflix and reinstalled, changed the firetv resolution, rebooted firetv

thanks!!!
