They show the DTM series.. they just dont show it during the season..
If I remeber correctly they televise it around October after Motorcycle season dies down..
They been televising it like that for a couple years now... trust me I DVR the whole season..
if you wanted to watch it during the season you can go over to Speed2.com
Edit: Just realized you want the season not the highlights.. but for the most part they show a fair amount of it.. think they skip out a few laps here or there...
