The ipod's dock output has a lot of problems.
Now back OT, I went into a big chain store about dec last year and asked if the ipod touch had video playlists (like the rest of the video ipods), he talked down to me (like how dare I ask such a stupid Q) and said that all video ipods had it...... I went ok and bought the thing.
He lied, for some odd reason apple did not program video playlists into the touch, so I tried to take it back but they whined and tried to not give me my money back...... I had to yell the Qld trade practices act at the manager to get a refund!
