I called my cable provider today (RCN) and asked what I can do. They offer a cable box for 9.95 a month which will work and offers a couple of hd channels. They informed me that almost none of thier channels are scrambled, because of this they also suggested I could use a VCR. Run the Coax to the VCR, then run either yellow/red/white or component to tv and use the vcr to change the channels. If you get a TV which will allow you to change channels but has no coax in they suggested an RF Modulator but I don't think the Westinghouse monitors can even change channels. I hope this helps.
My next question is, is there a DVD player out that can change channels
I have a vcr at home which would work but it's old and I'm afraid even the basic cable signal would suffer.
