When I was in Austria, the show I found easiest to understand was "Mein Mann kann". It was a game show where women bet on how well their husbands could complete a task - things such as number of pushups they could do or number of plants they could name.
If you're listening comprehension isn't that good yet, I would watch something you've already watched in English several times so you know the plot and the general idea of what the characters are saying. I love Orphan Black so I've watched the first two series several times in German. I can now hear what they're saying rather than relying on subtitles.
It seems like everyone's watched Friends and The Simpsons but comedies often have faster paced dialogue so it's harder to keep up.
You can always buy dvds with a German dubbed option - the German amazon has a wide choice.
