Hi All, Open question. I have a friend with a coolsat 8000 HD - 8PSK hooked up also. when he scrolls thru the antenae channels - very very slow. according to maual, a 300 Gig hd is the max storage that can be added - he has 500 Gig, might that have an effect on the slow scrolling of channels? he swapped out the 500 gig for 8 gig usb... it is notably quicker can anyone explain why? Sounds like a memory/processor issue to me. Thanx, adirondak.
