I am unaware of Dish giving any advanced notice of free previews of internationals. I just make it a point to check it out and hunt at least once a week. There are usually a few freebies about every month.
The international channels currently in free preview are 724, 727, 730, 748, 750, 752, and 904. Sorry I didnt include the names, but too lazy to look them all up
I check the guide everyday just in case I miss any goodies or free movies. Weeks ago, I tune on the Russian station and some martial arts action movies was on dubbed in Russian.
