I didn't know which forum this question belongs in, so it ended up here.

I want to have a TV running non-stop in our opening hours showing a regular tv-news channel. Every 15 minutes, i want to run a 30 second promo i made. Is that possible without having to start the promo every 15 minutes.

Is there any way I can set something up to play a dvd or videofile every 15 mins or so again and again and automatically switch back to the news channel whenever the promo isn't on?

In advance thanks
