Movies 'greyed out', will play in iTunes but not on Apple TV

Thanks for getting in touch. I'm sorry for my delayed response.

One thing to make sure of is that things are done in the proper order.

First, make sure that your external drive is mounted and available in Finder. Then, launch (or, quit and relaunch) iTunes. Finally, connect via your Apple TV.

If you do things in that order, are your videos playable on your Apple TV?

No, not the greyed out ones. When I first installed tunespan all was ok. Over time though more and more become 'greyed' out, and won't play on Apple TV but play fine in iTunes. Recent additions are also fine but older programmes grey out and won't play on Apple TV. Thanks

Does this continue even after restarting the Apple TV?

Also, could you possible send me a picture of these greyed out videos on your Apple TV so that I know exactly what you're talking about?

And, are you accessing them via Home Sharing? Or what?

Screen shot on original post is itunes. Attached is what shows on Apple TV. Accessed normal way from iMac using home share. Thanks
