I have a dish 500 now but when they install the 622 with the 1000 will it still support my 501 and 301 along with the 622 I only have one line running to the area where the 622 will be.They told me they would put a splitter in then connect it to the TV1 and TV2 on the 622 so I could watch one channel and record one at the same time.I live in McKinney Tx north of Dallas
