I want to record analog channels with my VCR - wouldn't adding a splitter to the incoming cable line degrade the signal or interfere with any information being sent back to Comcast. Just installed DVR DCT3412/digital service and have HDTV with VCR/DVD combo. Can't record through VCR now.
The loss of signal from a splitter is insignificant, unless you already have a poor signal. Just use RG6 in all your cable runs and you won't see any difference.
