Advertisements Can anyone explain to me how TiVo's OTA Channel Scan is supposed to work? I'm in Chicago and we have recently been asked to rescan due to the repack. I rescanned and TiVo showed me all the channels I get. However, several of those channels don't exist/don't have adequate signal strength. It also left out many channels that do exist and come in perfectly clear. I guess my question is...do I have things configured improperly? Or is the Channel Scan function on TiVo's just broken? Does it even look at signal strength or does the 'scan' just load data based on location? I get it if the data is wrong/hasn't been updated...but if it's actually scanning...it doesn't work.
