I have 2 Pro series DirecTV receivers with DVR and a Trac Star in-motion dish. We had to get the extra box to allow 2 receivers and I am OK for the time not getting HD signal. I have not had any issues that I am aware of when traveling and the in-motion works very good. My opinion is the Trac Star in-motion system works much better than the KVH. I had a new KVH on my old bus and this bus has the Trac Star so I got the back to back on the two. The one plus to the Pro series receivers is the built in cooling fans. I had lots of over heat problems with the older units and no internal cooling fans.
