Contact iTunes

How? Is there an email address or a web page where one can do this?

Yes, I get this sometimes also. Don't know why, haven't bothered to find out. I have found that if I sign out of my account, then sign in, it's all good for a while.

I'm having the same issue with ripped from my dvd/blu-ray collection. It's only the more recent rips, the older ones are still working ok. I'm still trying to work out what the non-working ones have in common.

One possibility is that they have both dolby digital as well as DTS and DTS-HD sound tracks (I was putting them on to prepare to a future device that support higher fidelity sound formats).

These rips all work fine directly in iTunes and were working before the TVOS 10.o update, but now seem to be broken on Apple TV.

We can't discuss anything relating to ripping commercial DVD/Blu-ray discs here

Point taken, vazandrew.

In any case, what I am trying to say is that some locally hosted content from my iTunes library that previously worked is no longer working with the new OS version. It still does work directly in iTunes.

I think it may be related to some aspect of how it was produced. (sound tracks, etc.)

Perhaps, we just cant get into it here
