hi all first. I've a nwza816.I bough it one week before.I can listen music good with no problem but i cant play videos coz Icould not find avc format vdieos or any converter. How can i convert my videos to avc(h264) format? or how can u watch your videos on nwz816? i think this is a big problem Sony did not give me any video converter. and i could not find any. And couldnt find any video problem in this forum. don't u watch videos on your mp4 player? Thanks for all ansvers and sorry for bad english
