I was playing some video I took from my X to the TV & it seems to work sporadically. First I got no signal, then I turned the phone off & on again & somehow it started working. I took some video over the weekend & am trying to play some video and I'm getting a message "Not Supported Video". I can't get any video to play now on tv (have the vid set to 720p 50hz). I have a Sony DLP 1080I. Can someone help, here?
