However, it may be not the easiest task to find a show in Ukrainian on Ukrainian television as there are too many Russian series and movies (they are broadcasted with Ukrainian subs) and Ukrianian talk shows in Russian. That's why news channels and national channel seem to be your best choice :D
It would, it's more about English grammar tenses. But in this case it's more like "Do you watch.." in generally. "Are you watching.." should be used more likely for one certain channel for a partical time "now", for instance.
