Catalina TV App and Apple TV streaming Home videos

Hi,

just trying to work whether something is possible now.

Before I updated to Catalina & the TV App, I used to 'stream' Home Videos from my computer in iTunes to the Apple TV box (1st Gen). I could access them via the Apple TV box, under Computers, loading my iTunes library and select the Video I wanted to watch.

I cannot do this now. (but can via Air Play, but that involves going into the office and pushing the Video to the Apple TV box.)

Do the newer Apple TV boxes (3rd and 4th Gen) restore this functionality? I can go and buy a newer box, but none of the local shops can answer this question.

thanks.

J.
