The Sony RDR-GX7 can record video and audio to blank DVDs, using two types of rewritable discs, DVD-RW and DVD+RW, as well as write-once DVD-R discs. The unit has a front panel DV input jack (also referred to as iLINK, firewire or IEEE1394) for one touch dubbing from Mini DV and Digital 8 camcorders. Three line inputs (two on the rear and one on the front) allow you to record from several sources.

Recording Speeds
You can select from six variable bit-rate speeds when recording a DVD. The picture quality improves as the recording time decreases. The recording speeds and approximate recording times on a 4.7GB blank disc are:

Recording Mode: Recording Time
HQ: 60 minutes
HSP: 90 minutes
SP (Standard mode): 120 minutes
LP: 180 minutes
EP: 240 minutes
SLP: 360 minutes

One-Touch Dubbing
You can transfer the entire contents from a MiniDV or Digital 8 digital video camera to the GX7 with the press of a single button. The recorder, through its DV input jack, controls the camcorder from start-to-finish, from playing the DV/Digital 8 tape to stop and rewind. A single i-LINK optinoal cable is required for connecting the camcorder and DVD recorder .

TV Tuner
The recorder has a built-in 181-channel TV tuner. Like a VCR records to a VHS cassette, TV shows can be recorded to blank DVDs for time-shifting or archiving. Once the recorder has been connected to the antenna or cable, the Easy Setup guides you through the steps of setting the time, date, and searching for receivable channels.

Recording TV Programs: The RDR-GX7 offers several ways to record TV programs:
Manual Recording: Record the currently tuned channel until you stop the recorder or the disc is full
Quick Timer: Record the currently tuned channel in 30-minute increments up to 6 hours.
Timer Recording: Set the timer for a total of 30 programs up to one month in advance. You set the date, time and channel of the program manually.
VCR Plus+: Enter the PlusCode number for each TV program you want to record. The date, time, channel and program duration are automatically set.
Synchro Record: Set the recorder to automatically record programs from connected equipment that has a timer function, such as a satellite receiver.

TV Virtual Surround
When you connect the unit to a TV or a stereo receiver, TV Virtual Surround (TVS) lets you enjoy surround sound effects by using sound imaging to create
virtual rear speakers from two speakers. This can be done using digital (Digital PCM) or analog signals. There are 4 TVS modes (or you can turn TVS off):
Dynamic: creates one set of virtual rear speakers (effective when left and right speakers are close to each other)
Wide: creates five sets of virtual rear speakers (effective when left and right speakers are close to each other)
Night: large sounds, such as explosions, are suppressed, but quieter sounds are unaffected.
Standard: creates three sets of virtual rear speakers (effective when left and right speakers are separated)
