Great app with a small gripe

After the confusion between "First" and "ARD Mediathek" app was cleared, I was finally comfortable access my new FireTV in offering the ARD.
The navigation works well to find your way quickly.

Only a small hook has been found and that bothered me a little. but I'm not sure if the error on the app or on FireTV located. When I see a stream and in the household, a download is started, then suddenly increased the Sttream. Only a successful download or waiting time leads back to ruckelfreiem video enjoyment. In other streaming apps I could not find such behavior. Although the ARD app is certainly not comparable to the Instant Video offer or max cathedrals, Watch Ever or Netflix.
