The Pinnacle PCTV HD Pro stick is a neat little USB tuner that supports over the air HD signals (ATSC) as well as standard definition content from cable or satellite providers. Included is software that lets you do your typical Tivo things like record, fast forward, and rewind TV. Sit back and watch from a far with the included remote and take your media with you because you can save direct to DVD, DivX, iPod, and PSP formats. Not a bad for a $130 way to add digital video recording capabilities to your laptop. There is also a Windows Media Center Companion package for an extra $99 that will bring the over-the-air HD goodness to your media center. Expect to see these products out in October.

UPDATE: The Media Center Companion is for people who have Microsoft Windows Media Center Edition but do not have the remote control or the receiver. The PCTV HD Pro stick comes with its own version of recording software, the Pinnacle Media Center, and a Pinnacle Media Center remote (not an MCE remote). However, both are listed as compatible with Microsoft Windows Media Center Edition. So, if you've got MCE and would like to add either HD or SD to your system, these might be the products for you. If you don't have MCE, stick with the HD Pro stick or the PCTV Pro USB (ATSC and NTSC respectively). Thanks for the clarification, Stephen.
