The DVR4200 is compatible with standard CDs, audio CD-Rs and CD-RWs, and discs encoded with MP3 audio files. Using its coaxial digital-audio output, Dolby Digital 5.1-channel signals are rerouted to a Dolby-decoding AV receiver to enjoy stunning surround sound from movies. When used with a compatible receiver and a six-channel speaker system (left, center, right, left/right surround, and subwoofer), the player puts you in the middle of the action. The unit's Virtual 3D surround sound can also simulate surround effects through an existing pair of speakers.

The DVD player offers standard composite-video outputs (two), S-video (one), and premium component-video outputs (one set, three RCA jacks). The VCR section offers two sets of composite-video inputs, one composite-video output, and one RF (cable-type) input and output. For audio, two sets of stereo, analog-audio RCA outputs are for the DVD player (one of which doubles as a VCR output), while the VCR accepts two stereo analog-audio inputs. A coaxial digital-audio output routes DVD audio signals to an AV receiver. A convenient child lock protects the front panel from fingers, toast, and other nonmedia, while the included remote control operates both the DVD and VCR features.
