As I stated in an earlier post, I to was stricken by the horrible speed and conversion of my wmv files when downloaded to my 80. Well today I called Zune support, and posed the question to them.What program will allow downloads to be added without conversion, and was told the proper format for both of my zunes (30 & 80) would be mp4 video. I converted the movie "War" to this format and downloaded it to my 80. Aw man it was a wonderful thing the files was transferred without conversion quickly, "saints be praised"
So imho mp4 video is the way to load your videos as I have and will
"Thanks for your support"
