I need help. The following has been posted on numerous forums and I am totally confused by various conflicting answers. Hopefully, someone has experience and can assist me. The following is my dilemma: Please allow me to preface my question by saying that I spent from 1110-1524 today on the telephone with a Dell representative attempting to solve my problem only to be told after 4 hours that my tuner does not support a digital signal and will not be replaced as a result of purchasing this and an E521`online. My packing list list the tuner as a Dual TV Tuner Q/Remote, TVT3, MCEO5,DIM. My satellite system is from Dish network utilizing a DVR 622 receiver. I don't recall reading that this particular tuner would only support analog signals and not digital signals. Purchasing the proper tuner is not a problem, but the problem I have is that this wasn't made available when I placed my order. Just curious if anyone else has a similar problem. Also, not pleased that I could not talk to a supervisor at Dell, only listen to a relayed message through the lady who did her best to assist, albeit obviously limited in her expertise. Otherwise, it wouldn't have taken almost four hours to arrive at the conclusion that the signal or lack thereof was the culprit. When I contacted the Dell Community Forum, I was told that this TV tuner should work as is. I am now more confused than ever. Any assistance appreciated.
