“USB reading problems I have trouble with playing music from a USB flash drive. All music is in MP3 format. It will play for a minute or so, and then quit playing and just say "Reading..." I'm on my second stereo, and it has the same problem. I've tried 2 different flash drives. I tried putting on a handful of MP3's and I've tried putting on several gigs of mp3's, all with the same results. Anyone else having this trouble?”
