I had an older iMac that was still using iTunes, I have hundreds of gigs of downloaded TV Shows and Movies that I've purchased that I use for Home Sharing on Apple TV. After upgrading to my new iMac and transferring my downloads back into my library, the icons/thumbnails are all jacked up. They display with the portrait picture instead of the landscape, they still play but it looks much uglier on the Mac and Apple TV now when they didn't look this way before the upgrade, is there anyway to fix it (even if it's a 3rd party app)? Like I said, it's a lot of downloads, I'm sure if I deleted and re-downloaded it would solve the problem but I didn't really want to deal with that if I could avoid it. Thanks in advance.
