Skude. Have you sent your distributor the results of a checksum test? If your Audya were sent into me for repair the first thing I would do is format the hard disk, reload the drive and flash memory.
I need to correct you on something - "many people" do not have a problem, you have to remember that on a forum such as this the only people that write in (apart from the core members) are those with issues that their retailer or distributor have not resolved.
