Does anyone know if there is such a thing as a receiver that takes a cable card and doesn't require a PC to function (outputs SD or HD video, doesn't matter) There are some DVRs, and some receivers/tuners that interface with a PC, but I can't seem to find this. I'm running into problems with an overheating cable box (DC-757X) that is in an equipment rack with a lot of stuff. I had a DCT-2000 replaced since it had overheating issues but the new box is much worse. All these stupid boxes have a max operating temperature of 104F and no internal fan. I have to blow a big fan directly on it and STILL overheats. Directv receivers (one H20 and one H24) seem to have no problem with the temperature at all. I'm worried that if I'm having this much of a problem now it is going to be really bad in July when that room is 10-15 degrees warmer!
