I recently took down my HTPC because we weren't using it and rebuilt a gaming computer for my son. Obviously after not using the HTPC for 6 months, my wife has decided she wants to be able to play stuff off USB. The TV is a lower end LG and while it does have a USB slot, it won't play video files, only music or pictures. 1)Is there someone I can buy that isn't too pricey to be able to play video files from the USB? 2) Or would it be better to run a 50 ft HDMI cable from my new PC to the TV and watch that way?
