I have a SlingBox that I have connected to our home cable box/DVR when we leave for the summer and head up to the Georgia mountains until October. I have had no issues with the SlingBox or local CG Wi-Fi and the HD picture. I should put in a disclaimer regarding local CG Wi-Fi as we use a Wi-Fi signal extender). It is great having all the local TV stations (hurricane updates since we live in FL), and the Ray's games along with DW's recorded favorite shows to watch anytime.
Dish also has a receiver that has a SlingBox built into their receiver, but I would have had to pay for 2 accounts, one at home and one for the TailGater on the TT (used when we are dry camping). We only turn on the tailgater for a few months each year.
Just my thoughts,
