I synced about 20GB onto my player with Beta13 - took a while, but no errors. I alternate between USB and Ethernet on Windows 2000.

I don't believe there is a general 75% error rate with synchronisation, so we need to determine what the common factor is. If it's not interface or PC then perhaps you're using emplode in a different way to others, somehow.

Do you know if 1.03 works OK for you?
