I was not in chennai this weekend. This morning, once I came back, noticed that my cable operator moved to a new provider as I mentioned earlier. I thought it is completly changed and I need to buy a new STB. Later by 8am he swiched back to SCV. At 10 my STB wad showing nothing but signals are there in analog mode with same SCV. Not sure what is going to happen. One additional info is that there is a local channel called VTV in the analog channel line up at the time when my operator changed singal. As per this channel advt, it is broadcasted from Alanthur and available in Adambakkam and Velachery as well. I am from Velachery and so it was available for me. Now some of you people can tell from which MSO is the signal from.
