I didn't have internet in my house when I got Directv installed 6 months ago. I have to HR-24 receivers with MRV. I see that on Directv.com they want you to have professional instillation for the internet which was around 75 dollars. My question is, is it really that hard to get the internet hooked up to HR-24 receiver's since it already has the DECA built in them? What would I need to hook them up or should I just let Directv hook them up?
