I have had the same problems with my Mk 2 player from day one - using both USB and ethernet. I am running Win98SE, on an ABIT P3 500 (real Intel), consumer image 1.0. I can often get away with syncing a single album (though not always) but as soon as I load up 2-3.. I get sync issues. I have also had the system subsequently lockup while playing (~20 times).

I've had the unit a month... and it's been a very frustrating month. I'm glad to hear I'm not the only one. Maybe we can get a fix soon.
