Sending video from iTunes to my ATV2 no longer working

[mclld]

I can stream my library but I used to be able to open up itunes on my computer and send it to my atv that way, now I dont see any option and the video just plays within itunes

Mac user? Windows? On my Mac I start the movie and then airplay it straight to my ATV2.

Have you tried resetting your router?

Windows and no I have not reset it. I did notice yesterday that file sharing had been turned off on my pc for some reason, I turned it on and then I could stream my library again but i still cant send from itunes like I was able to before
