The Zero 4K is a zapper and supports therefore only codecs provided by Sat/Cable providers like mpeg-2 mpeg-4 H.265/HEVC compatible
Like the DM One UHD you cant mount an internal HDD so therfore no need for any avi support.
I can agree that this should be better informed by Vu+ and sellers of this Device.
But its marked as a UHD Zapper and no provider send any channels in avi format.
I dont now if you buy the PVR-Kit if you get support for avi containers but as a zapper there is none.
