LG 5.1 DVD Home Cinema System

  • HT303SU

Key Features

  • Maximum Playback
  • Dolby TrueHD and DTS-HD Audio
  • Progressive Scan
  • The Benefits of Audio Specially Tuned by Mark Levinson

Maximum Playback

With the development of multiple audio and video disc formats, it is important to choose a DVD recorder that can play the mall-with LG you can. Not only play back all leading audio and video disc formats, such as DVD-Video, VCD, CD and MP3 audio, but also DivX, JPEG, and WMV files.

Dolby TrueHD and DTS-HD Audio

Sound quality and audio detail with Blu-ray is vastly improved when compared to DVDs because the raw audio isn't compressed. That means there's no loss in quality and all the details of the sound appear as they would in the cinema. High-definition audio comes in two formats: Dolby TrueHD and DTS-HD Audio. LG's Blu-ray player works with both, so you'll always experience the finest sound.

USB Direct Recording

With USB Ripping, you can connect a compatible MP3 player to the LG product’s USB port and record or ‘rip’ music from a CD directly to the MP3 player. The tracks will be copied onto the MP3 player in the order they appear on the CD. This great feature enables you to copy music on a MP3 player without the need for a computer!

VSM (Virtual Sound Matrix)

VSM enhances the listening experience from a home cinema system, by enabling the sound to travel more smoothly around the room. This is done by creating ‘virtual speakers’ that direct the sound. For example, VSM on a 2.1 home cinema system creates a ‘virtual’ 5.1 surround sound effect so that the sound appears to be coming from the back of the room.


DivX is a file format that allows movies to be compressed and fit onto a CD, as a DivX movie is about 8 to 12 time smaller than a DVD. DivX playback on LGs video and audio products allow you to download DivX movies from the Internet onto a CD or USB stick, to then enjoy in the comfort of your living room.


Supports playback of MP3 files recorded to CD-R/RW.
