Unlike the 442 in its ability to not only play back a wide variety of media formats but also record digital audio and video, the Creative Labs Zen PMC is purely a portable AV player with video formats limited to WMV, ASF, and AVI. It has just 20GB of storage space, half the capacity of the 442’s 40GB hard drive. The Archos AV420 features AV playback and recording like the 442, but has only half its drive capacity (20GB compared to 40GB), less battery life for video playback (3.5 hours compared to 5 hours), and a complex video conversion process.
