yeah you need side by side mkv for great quality, most new tv's will play them straight off a usb drive so no need for a media centre.
I wouldn't call it "great quality"...problem with SBS MKV (assuming of course they are all personal rips of Blu-rays you have bought) the horizontal resolution is halved, plus I presume many of them don't come with the DTS MA or TruHD soundtrack.
I personally prefer buying the 3D Bluray - proper 1920x1080 3D image and full resolution sound track![]()
Yeah your right about the resolution and the soundtrack, they do however most of the time come with DTS, which is still good, and for free, you can't complain.
But then you could always get the full image and burn it to blu ray yourself.
