TVtonic is a Windows application for finding, watching, and downloading online video. The software can be integrated with Windows Media Center, which makes catching episodes of RocketBoom just as easy as recording episodes of The Office. But for financial reasons, Wavexpress, the company behind TVTonic has decided to retire the service.

If you've already installed TvTonic, you can still use it as a video podcatcher by subscribing to RSS feeds. And the download link for the Windows XP version of TVTonic still works, but the download link for the Windows Vista version appears to be dead.
