Currently have an HR34, HR24, H25 and two C31s. After initially working fine, I've grown tired of the C31s and plan to replace them with H25s. Not sure if my Slimline SWM dish and the 8-way wide band splitter are going to get it done though. From what I gather in threads around here, it seems like I need an equipment upgrade in order to feed the new H25s, because they wouldn't be sharing a tuner with the HR34. That about right? If so, should I set it up through Directv or give it a go myself? If I don't have to touch the dish, I'm fine, as long as I have the proper equipment. (The dish is on the very top of our roof, three stories up and my ladder isn't that tall.) But I'd hate to screw something up for what is otherwise - aside from the flaky C31s - a well-working setup. Thanks in advance.
