Was under the house trying to fix a leak and as I was finishing up, I noticed a cable running toward my old TWC box outside the house. Upon further investigation ( by following a maze of cables), I realized a Dish installer ran a cable for a 3rd TV in the kids room through a splitter from TWC. Honestly, I couldn't decipher what cable is going where and how they did it... It's only rated 5/1000MHz. Is this a big deal? I mean, will this degrade the PQ? It looks kinda shabby but it IS for a 25" TV in my kids room so unless it'll make a huge difference, I'm not gonna worry about it. Could I just buy a higher-rated splitter that's for sat. use only and it give better PQ? Also, I noticed the cable going INTO my receiver from the dish is barrell-connected..Is this killing my PQ on my 50"? It seems fine, but I obviously (unbeknownst to me) haven't been watching my TV through a direct, single connection. Man, I got shafted on a hookup. Next time I need to supervise the installation, I guess. Heck, I might even call to get someone out here to completely reinstall my whole system. A $100.00 service call is pretty cheap considering the work that will have to be done and I'm no tech. guy!
