Hello,

I'm wondering if anyone who has music a movies on an Airport Disk (Airdisk) volume experiences extremely slow syncing via iTunes (7.6) compared to actually copying the file onto the local machine and then copying it to the iPod (via Manually Manage Music and Videos).

I decided to test how slow it was by copying a 1.36GB movie (.m4v) on the Airport Disk to my iPod (touch) using iTunes and copying the movie to the local disk and then copying it to the iPod from there.

Airport Disk -> iTunes -> iPod = 3 hours and 10 minutes*
Airport Disk -(14 minutes)> Local HD -> iTunes -(5:33 minutes)> iPod = About 20 minutes

* I should note that the Airport Disk -> iTunes -> iPod was cancelled after it only reached 50% completion in an hour and a half and thus I arrived at 3 hours and 10 minutes by doubling how long it took to reach 50%

I really don't understand why going through iTunes from a remote disk slows down the transfer so much. Clearly the hardware is capable (I'm using a iBook with 802.11g) since copying it to the local HD and then to the iPod was 15X faster. Does anyone have any idea why there's such a discrepancy? Are there settings I can tweak?

I should also note that QuickLook-ing files on the Airport Disk is also unnaturally slow, even 100kb JPEGs, when it takes a split second to copy to the local disk.

I'm running Mac OS X Leopard 10.5.2.
