First apologies for being ignorant - I'm working on it! I purchased a new Sony receiver and have successfully got the speakers working; ipod working; TV thru cable box to speakers working. I also have the audio to my DVD coming thru my speakers. Unfortunately I do not have video. I suspect that this has something to do with my Cable (Knology) remote's setting - but it could be something else as well. Any ideas? I am a recent widow and my husband used to "do the electronics" - now I'm trying to "own my toys". Thank you in advance...
