I need some help! A couple of receivers in my setup are responding incredibly slowly to button presses, and it is starting to drive me nuts!! I have five receivers (3 HD DVR and 2 regular HD) on an MDU account, all running SWM from a dedicated 8 port SWM multi-switch. The two HD receivers and the HR24-200 are all running normally; however, the HR24-100 and HR22-100 are EXTREMELY slow to respond to certain button presses (i.e. 30 seconds to a minute). The button presses most commonly impacted are channel changes (either through a number entry or channel up), Guide, Info and starting to play a program from the playlist. When I enter a channel number (e.g., 206) only the first number registers with the receiver (after 30-60 seconds), but after the receiver responds i am given a short window (about a minute I would say) where the receiver responds to all button presses in reasonable fashion. Once a receiver is playing a program (either locally or thru multi-room) trick play performance is slightly slow, but manageable. All of the receivers on the account are 2 years old, other than the HR22-100, which i received as a replacement receiver from Directv about a month ago for a failed hard drive on an HR21 (coincidently, that receiver was also responding very slowly to button presses). Both the HR24 and the HR22 pass all tests other than phone line (I do not have one connected). Since both receivers are passing all tests Directv will not send me a replacement for either box. Furthermore, since this is an MDU account, Directv cannot send someone out to my apartment, and instead refers me to the MDU operator. I am somewhat skeptical of having them come out, since the last time they were here they claimed that they did not need to deal with my broken box since it was purchased from solidsignal, even though it is a leased box (i got two receivers from the MDU operator when I signed up and purchased the other three from solidsignal). Since I have two receivers exhibiting the same behavior I am wondering if the problem is something with the MDU environment. If I have to I am willing to purchase replacement boxes from solidsignal, even though I think somebody should take care of these issues since all boxes are leased. Thanks for the help, and sorry for the long post!
