How do I fast forward live TV? I have Dish network, help!?

[cookies]

Okay, so my family just got Dish Network installed and I'm really confused. Whenever I watch a movie I can record whenever I want and how much I want and when I watch live news I can pause and rewind as far as 2 hours back but I can't fast forward 2 hrs ahead...? Is this normal?! Other than that it's working great and I love it but I wish I could tell what's going to happen on the news like it's so suspenseful because there was a girl missing the other day (can't remember her name) and I wanted to go ahead so I could see if she'd be found safely. (She was okay but I had to wait it out and I was worried the whole time) Will they ever upgrade to this feature? Thanks in advance
