Hi after many years my CRT TV conked out on me. So I needed another TV so I bought Samsung UN32D5500 it is store I knew I could return it if necessary because I have special needs for this television, getting it to work with my 40 year old Bose speakers. For reasons not pertinent to my question this didn't work out, so I am seriously looking at Sony Google TVs. I have an incredible quality MKV video which I have been using as a test video on my handy flash thumbnail drive to go to the stores and compare TVs. According to the Sony store in Denver that I visited all Sony TVs are only designed to run MP4 videos from the USB port. But watching a video about Google TVs which mentioned Windows media player as application built in to these TVs I started to think otherwise. So can I with nothing more than a USB flash thumbnail drive in hand have salesperson's demonstrate a visually spectacular MKV test video on Sony Google TVs, if this salesperson can know how to do it with a little instruction from me via you? I don't care if it runs on Windows media player or something else it is possible to install on a Google TV. But it has to be simple enough to get this salesperson to do it. Incidentally the reason I am looking very strongly at the Sony Google TV is a 32 inch model is now $500, but I had some quotes from Google shopping site which said the 46 inch model was only $600. The Sony representative at the Sony store said you'll never get it at that price. Is this right will you never get a new 46 inch Google TV for $600? I don't think so but I know I saw what I saw.
