I had the same problem, iTunes freezing after 8-9 seconds of play and just overall being laggy when Ipod Classic was connected. I myself have a 80GB.
_*Heres a temp Solution*_
The fix is simply changing the Drive Letter Assignment for your IPOD.
So to Reassign/change the drive letter your IPOD is currently using follow these instructions (

+_Basically go to_+
Control Panel > Switch to Classic Mode > Go to Administrative Options > Computer Management > Storage > Disk Management > Right Click your IPOD > Click "Change Drive Letter/Path" > Then choose the Letter from the Drop Down Menu.
I chose "I" for IPOD and I never use more than 4 USB ports. If you have many Partitions or USB ports being used by storage devices you might have to go for a "higher" letter such as "X".
After this is complete, just eject your IPOD from itunes, and close itunes, and reconnect your IPOD. I did this in conjunction with Authorizing my computer as told above, but the Authorization didn't do anything for stopping the freezing.
_*The Reason*_
Windows is unfortunately messing the way the IPod syncs with your computer because of the drive letter assignment. Many of you use your USB ports with USB keys and External Hard drives, and these are essentially the things that are hindering the syncing of the IPOD because windows is mixing the External Hard drive and IPOD up.
