Roxio has released version 3 of their DVD and video conversion utility Popcorn. The biggest new feature is probably the "exclusive TiVoToGo support for the Mac" that lets you burn TiVo recorded shows to disc or convert them for playback on other devices. However, other improvements include the ability to create compilation DVDs and custom DVD menus as well as improved Apple TV and iPhone/iPod support. Popcorn is $49 and is available now.
For my own money, I think the the only compelling feature of Popcorn is the TivoToGo support. Unless that's a big deal for you, I think you'd probably do better with VisualHub ($23.32) plus Handbrake (free), as the ffmpeg based conversion of the former is considerably faster than the QuickTime based conversion that Popcorn appears to use.
