1.How do you view the JPG and video files from the USB (memory tick). I tried pluging the cable on monitor out at the back of the system (AR702TT-AD) to the AV input of the TV but didn't work 2.How do you skip songs played from memory stick without going through them one by one (e.g. your playing track 10 from a stick that carries 200 songs and want to go to track 100)
