I just bought the Roamio last week. After going through the forums, I think I came to the conclusion that nobody has a fix for the Roamio not tuning correctly. Tivo will not take responsibility for it and the cable (mine is Time Warner, and they have no interest in helping) companies won't take responsibility for it. Am I correct? Is it worth waiting for a fix that might never come or should I just bite the bullet and get a TWC DVR?
