I had exactly the same problem as Kris (#7) a couple of days ago but since downloading the w32codecs ubuntu-restricted-extras from Medibuntu today (see https://answers.launchpad.net/ubuntu/+source/rhythmbox/+question/32014) I only seem to get the PTP Layer error a803 message.
I've also noticed that I only get this for tracks I've downloaded (from Amazon). Podcasts and tracks ripped from CD appear to transfer with no problems.
