From eBay:

"In the next few days we will be updating the Pre-Filled Item Information within DVD & Movies, as well as updating Item Specifics and updating Pre-Filled Item Information within some Music subcategories. The planned changes will both update current values for Pre-Filled Item Information, as well as add new ones, to reflect recent changes in product information.

Sellers who use Pre-filled Item Information when relisting or revising items in these categories may receive the following message that their original Item Specifics and/or Pre-filled Item Information have changed: The Pre-Filled Item Information for this item has been updated with the latest information. Please review the changes. We encourage sellers who receive this message to double-check their listing for accuracy before completing the listing.

We have started thread a thread on the Movies & Memorabilia board [http://forums.ebay.com/db2/thread.jspa?threadID=200085221 to detail the DVD & Movies changes, and another thread on the Music & Musicians board to detail the Music changes."
