Roxio has quietly released Popcorn, a new Mac OS X application that helps you make high quality copies of non-encrypted DVD-Video discs, disc image files, and valid VIDEO_TS folders from a hard disk. The software allows you to compress an entire 9GB dual-layer DVD-Video to a standard 4.7GB DVD disc and “maintain high video quality and full audio fidelity.” Popcorn supports multi-channel audio (such as Dolby Digital 5.1), multi-language content, NTSC and PAL video, and widescreen or pan/scan aspect ratios.
