I upgraded from a 510 DVR to 625 DVR. Does the LNB have to be changed on the roof to the Dish Pro Plus LNB to make this 625 work? And do I have to run another RG-6 to the roof? Currently only have one RG-6 to the roof, as was used on the 510. Do I have to also re-aim the dish...............?? Was using 110 & 119 on the 510 DVR, and is the satellites the same for the 625?? Help ???? The 625 will not operate at this point......tried to also use a 311 and no work either??
