Call your provider. We decided ours was too high and I bought an antenna. We get 60 channels. Not all are english but all the local channels and then some. So the wife called to cancel the tv part but the guy basically cut the bill in half so she kept that as it was half what we were paying. We don't get any of the movie channels or some of the fancy channel but we get all the local channels and then some , and internet.
If i had time to figure out hooking the computer to the tv the I'd just stream the stuff I want right to the tv.
