Just noticed this today for the first time. Clicked on it & got the message "The videos on ReadyDLNA:C7000v2 PC's Now Playing List could not be displayed because it is unavailable. Press LEFT to return to the My Shows List.". I have many shared folders containing videos on my Windows PC that I have no problems accessing through other devices assuming this is what it is for. This must have been added during the latest update because like I said, I just noticed it. I'm assuming it's for streaming videos from PC's. I do have Tivo Desktop on my computer which runs in the background. Any help is appreciated. Thanks!
