goes without saying, but just in case you're inclined to waste a few gallons of precious regular unleaded searching for a tuning adapter, don't. The National Cable & Telecommunications Association (NCTA) and TiVo have jointly issued a release to inform the public that "several manufacturers of switched digital external tuning adapters have submitted products for formal testing at CableLabs." On the positive side, this means we're inching closer to seeing these devices hit store shelves, but sadly, it also means we're not done wading through red tape just yet. For those unfamiliar, these newfangled "tuning adapters" will enable TiVo Series3, TiVo HD and certain one-way set-top-boxes that utilize CableCARDs to "access digital cable channels delivered using switched digital (SDV) technology."
