I am pretty much a newbie to DIRECTV and am technically challenged. I have recently noticed a problem and was wondering if it is normal or something I should call my provider about. Basically, lately I have been getting brief pixelations and a message saying the signal is lost or something like that. It doesn't last very long, just a few seconds but it happens pretty often...about every 10-15 minutes. I don't have an HD box or an HDTV and the problem seems to happen on all channels although I tend to mostly watch local channels. Any help will be appreciated so I can figure out if I need to call for service. Thanks.
