Hey guys Just wanted to post a little review on this nifty little box I just purchased. http://www.glorystar.tv/shop/item/AC-CTMM10 I grabbed it off E-Bay and got it yesterday. Took me about 45-min. or so to hook up. I was trying some of the lower channels and was getting alot of snow. When finally put it on 125 it worked great. The picture was much better than I expected and sound came through very good. It only has one RCA for sound so I used a splitter and connected the L/R to the one input. You just have to make sure that you connect your main cable line and the coax line from the modulator to a splitter/combiner and then branch off to the tv's. One thing to remember is that if your using a cable modem or pay per view the splitter/combiner must be bi-directional. So now every tv in the house can turn to channel 125 and watch whatever dvd,vcr,etc. I have connected to the modulator. Part's Express sells them along with the combiners at pretty good prices.
