So I had a service call yesterday to finally (I hope) fix my Sunday Ticket blackout issues. So far so good. (The solution was simply a new box to replace my 10 year old box, but hey it worked... so far). The tech was a very nice guy, and seemed to be a knowledgeable guy. Anyway.. The tech was asking me why I never fully switched to DirecTV and was still with cable. I didn't want to get too in depth with my personal reasons such as 2 year commitments and "buying" leased equipment, etc... So I told him one of my biggest reasons was that I wanted a DVR and how incredibly difficult it was to fish a second coax down my wall due to the roof pitch and little room in the attic. He said, "We don't do that any more. If you have a 5LNB dish, you can run DVRs in up to 4 rooms with only a single coax going to each room." Really? Now he spoke with a bit of an accent, but I think he called it a SWIM box...??? So... experts... tell me. Is this true? Is the technology reliable? What are the pros and cons? 1 coax for a DVR.... Thanks.
