Hello PerryM, I feel your pain, but knowing how to work with Files and Folders is essential. With your Media Player you have a Media Manager, and here you can add the Media or Favorites to access what you want. I also got the Firmware upgrade, and I was hoping it would solve my problem of not playing M2ts Files all I get is Sound. It didn't solve it, and you are right, no information on what it did. Well at least we know they are trying, and I have full confidence in Buffalo to solve our problems.
