My 5.0 generation video iPod has started to lag for a while, and it is getting really annoying. When I scroll and browse my music, photo, and video, the iPod just takes too long to load, which really annoys me. Sometimes just even browing music is a pain. I have tried restoring the iPod last night, but once I put all my music, photos, and video back in (around 10GB), it starts to lag again. I think when it has less music it doesn't lag as much. Does anyone know how to fix it?
