A disc player for someone who already has a FireWire chain and does not need modern video output. The lack of HDMI and the limited resolution are the reasons to look elsewhere for a main living room player.

Overview
A shelf in a study or spare room is where this Sony disc player earns its place, feeding a display through its FireWire connection instead of the HDMI link most modern setups expect. The tray takes Blu-ray media, and the chassis stays light enough to slide onto a narrow shelf. Video leaves at the listed HD resolution, so the picture it sends is not the full high definition a newer player would pass along.
Sony built this unit around a FireWire connection and a Blu-ray drive, which suits an older editing or archive setup more than a current television. The resolution ceiling and the missing HDMI port are the two limits that decide whether it belongs in your rack.
Who it's for
Someone maintaining an older FireWire workflow who needs a disc drive to read Blu-ray media. A household shopping for a main player to feed a modern television should look at a unit with HDMI output and higher resolution.
Pros and cons
- Reads Blu-ray media
- FireWire IEEE 1394 connection
- Light at five pounds
- Compact black and gray body
- No HDMI output listed
- Resolution tops out at HD
- No streaming apps listed
- No included components listed
Performance notes
Playback quality is set by the listed HD output and the FireWire link, so the signal path matters more than the disc itself. A display or capture device that accepts IEEE 1394 gets the feed directly; anything expecting HDMI needs a separate conversion step.

Frequently asked questions
Is the Sony RDRGX315 a Blu-ray player or a recorder?
The listing describes it as a disc player with Blu-ray media type and 720p HD resolution. No recording function is stated in the specs, so treat it as a player only.
Does the Sony RDRGX315 connect to a TV with an HDMI cable?
No HDMI output is listed. The only connection named in the specs is FireWire (IEEE 1394), so a television without that port cannot take the signal directly.
What resolution does the Sony RDRGX315 output?
The specs list 720p HD. That is below full high definition, so the picture will not match a newer player feeding a full HD panel.
How much does the Sony RDRGX315 weigh?
The unit is listed at 5 lb, light enough to sit on a shelf without reinforcement.
