I have an HR20-100 with the built in OTA tuner which I use to receive my locals. About a month ago our CBS affiliate, WINK-TV, changed from channel 9 to channel 50. I did a rescan, and all was well... for about a week. I lost WINK and had to rescan again, and all was well... for about a week. Could the OTA guide received off the satellite have the old channel information, and my reciver keeps "correcting" the channel? Is this something I'll have to live with until the data base is updated? Thanks.
