Apple Syncing problem..

Hi guys, having an issue and was wondering if you guys could offer me some advice to help solve it.

In short my I tunes cant seem to sync with my tv. i tunes is recognizing the apple tv but when it tries to sync it just hangs there and no files are transferred.

My setup is as follows:

Airport Extreme connected directly to the modem
PC connected to the above over wireless
TV connected to my network via wireless

I have been buying tv shows/movies/music via the apple tv and it was having no problem syncing those files from the tv to my PC. Its the other way around that seem s to now be a problem..

I saw on the apple support forums that the new firmware on the extreme could create this problem, but I rolled it back to the earleir version and am still having the problem?

Any help much appreciated!!
