Help with archos 605

I have just bought a archos 605 wifi and desperately need some help with syncing it.
I am using media player to sync it, but always about half way through it will just stop for no reason, I presume this is the only way to sync the music so it gets categorised under artist and album on the archos, unless anyone knows different, as when I copied it from mac, it was just listed under 'hard drive'.
Is there actual archos software that must be easier and more stable than windows media player?
