Some strange problem with my cable TV. I was connecting a new Sylvania DVR/VCR unit in my bedroom. I used to have a Sony DVD/VCR in that same place and the cable reception used to be just fine. First thing I noticed after attaching the new unit is that the signal quality is very poor. But anyway then I come down to living room which has the Comcast's digital set top box connected to the wall outlet. I noticed there was no signal on TV and box was displaying a 'this channel would be available soon' message. Usually that means some kind of bad or no connection. Before I went up to the bedroom everything was running fine. Did plugging in the DVR/VCR unit blow the cable circuit ? [more inside]

I am looking for a proven, simple and possibly cheap way to boost my mobile phone's signal. Inside my house I have no signal, however on the roof I can sometimes get a signal and make phone calls. I know there are repeaters, but does anyone know of a product that is tried and works well. Oh, and I am on Bell CDMA in Canada
Why is it that when someone has been on the phone a long time or it's off hook, the busy signal that callers get has no "click" preceding it? I've noticed this since the 80s and am surprised it still happens with all the changes/upgrades at the telco.
