Lance:
Some people are reporting that if they manually enter in the actual digital channel (including the decimal or dashed part), as opposed to the virtual/display channel, their tuner will go to the virtual channel and will manually add that channel into memory. My Sharp Aquos does this (and other Sharp owners have discovered this as well), even though it's not in the manual, and Sharp told me there was no way to manually add channels. Perhaps you've already tried both the actual and virtual channels already, but I wasn't sure from your post. In case it is helpful, the actual channels are available at

Hope this is helpful...
