Roxio Popcorn copies non-encrypted DVDs, disk images and VIDEO_TS files and compresses them to a number of other formats mostly for mobile devices. Even though the application lacks a proper startup tutorial for first time users, you can easily understand how to use it from the options on the left side of the interface. Roxio Popcorn reads DVDs, image files and Video_TS files. The program includes a media browser, which hovers in a separate window, from where you can look for the videos you want to compress. Unfortunately, this browser is limited to list view, which feels odd on a Mac, where you can browse folders by many different other views. Once you've selected the videos to compress press the big red button at the bottom right. It'll open up a separate window, from which you can choose the format you want to compress to. Advanced users will be disappointed to find that they are all presets and that video quality can only be set via a slider bar. However beginners should like being able to quickly choose the best format for your device such as Apple TV, Blackberry or Treo. You can select an option to fit to DVD compression and even create a compilation of VIDEO_TS files. If you're not sure of the format you want, just create a quick preview. Roxio Popcorn also lets you gauge to maximum size, such as 256 MB or 1 GB. You can follow the compression process thanks to the progress bar over the Dock icon. Roxio Popcorn comes with three additional applications. Tivo To Go, Disk Cover RE and a video player. The Disk Cover application is very intuitive to work with and already includes a number of templates for CD or DVD covers. The video player, even though a little basic, has a nice sleek interface and includes all the necessary playback tools. Tivo To Go is great for sending TV programs to any handheld device. Roxio Popcorn lacks advanced compression settings and a proper startup tutorial. However it makes for a very simple way of compressing videos to the mobile format of your choice.
