Years ago I used to have a slingbox, but had too many problens and had to re-program my router to port 5001 and other technical things I could not figure out. I now would really like one again. Can anyone tell me if the newer boxes are more user friendly do you still have to call the cable company to mess around with the router AND do the new boxes work with a sling catcher. I have 2 of them and always liked them. PLEASE! truthful answers about the product good and bad.
