You should be able to either use Windows Media Player or the desktop version of the sync app to sync up an iTunes playlist. The desktop app is fairly unstable though, and may crash while syncing, I've seen people have better luck with Windows Media Player.
For me on day 1 with an 822, I had no trouble getting the desktop app (on a Win 7 machine) to sync a 7 GB iTunes playlist. Maybe it would crash if I tried to sync a bigger list? (I have to get a micro SD card before I can move more stuff over.)
