ATSC Cable QAM Tuners - CableCARD or ATSC Ready

I have a Sony SXRD HDTV with integrated NTSC/ATSC/QAM tuners. I now have Time Warner basic cable service. TWC has recently taken over the Adelphia service I used to have. TWC has begun remapping the analog and digital channels to resemble what the rest of the Cincinnati TWC customers have. With Adelphia I was receiving local digital and HD broadcasts on subchannels of 128.x or 129.x of my internal tuner (I don't use a cable box or cable card). TWC has remapped the local digital stations to odd frequencies like 114.21, 109.7, 105.1, etc. When I discovered that they had been moved I ran my autoscan, and much to my surprise my scanner did not detect any of them. The frequencies were given to me by an engineer at a local TV station. When I enter the frequency numbers using my remote I can receive them, however my scanner can't detect them nor can they be stored in the TV's memory. Can you explain how this is possible. (TWC has since remapped these channels to coincide with their analog equivalents - eg. 105.1=5.1, 114.21=12.1 - which my scanner does detect. But I would still like to know why my scanner can't detect the old frequencies yet show them when input with the remote.)
