Hi All, Ok, so I get that 4K Blu-Ray players are better than streaming from Netflix, Amazon, iTues(?) and even Sky TV but..... are they better than streaming backed-up Blu-ray player content from a HD or NAS? Surely if a disk is backed-up losslessly and contained in an MKV for instance, then direct playing, with no transcoding, would be equal to a 4K disc no? If so... what 4K network players out there can rival a good disk player? Really appreciate your thoughts... thanks.
