I have the 6th generation ipod and had to upgrade itunes from 7.3 to 7.5. Prior to this converting quicktime videos for my 5th generation ipod worked fine. Now with 7.5 only the video is good the audio is pulsating static. It plays that way in both itunes and on the ipod. I have tried it on 3 different computers with the 7.5 itunes and the same thing happens. I use the same file on a computer with 7.3 itunes and it converts fine, video and audio. HELP I have a 6th generation video ipod that i can't use for videos.
