i have video in mp4. and mov. that won't play?
I have old video from my computer before i changed to mac. They are in mp4. format as well as some .mov format and I went to play one in the mov format and it tried to convert so I just tried to play and it will not. I am afraid to do much else I dont want to lose the files. What do I need to do to convert or play them. I used a couple free services and they gave and error or converted and still would not play.
