Okay, I will check out my TV after I remove the DTA. When I received a letter from WOW about Digital Transition, it didn't address anything about subscribers having old analog TVs and WOW assumed that I have one, despite the fact I told WOW more than a year ago that I have a HDTV that is able to broadcast HD channels. The letter made me assumed that as long as I have Basic Package (not Digital Value), I would not be able to view the channels after the digital transition/conversion and that I should get a DTA as soon as possible.
UPDATE: I removed the DTA, turned on the TV and got channels 53 to 93 all color bars with message that each of these channels has been transitioned to a digital format. I assume that happened after I activated the DTA at WOW website this morning. Now calling WOW customer support.
