Videos not Syncing Iphone 5

I bought the new iPhone 5 just 4 days back in India, after buying i updated my software to iOS 6.0.1 and I tried syncing mu phone to the Mac and all the songs and photos are syncing properly but from iTunes but my videos when i try to sync them they simply do not sync. I mean i checked them and synced then unchecked them and synced but nothing.
