Why is my cache only about 1 week out? Why is my Program Guide to Jan 17, but I can't find shows on the 15th or 16th? Can someone explain how this works. I am trying to set up some new shows that should be in the guide, but TiVo can't seem to find them. i.e. "24", my info says that the guide goes out to Jan 17 but "Day 5" is only listed for the 15th and the cache is only about a week out? Thanks!
