Does sony DVP-S725D Play CD-R VCD? : LUSENET : Video CD : One Thread

Does anyone know if Sony DVP-S725D model plays CD-R video Cd? if so what kind of media is recommended?? Did anyone test this particular model


-- Sam (, November 14, 1999


I don't think so. From what I've heard the later model Sonys only play cd-rw discs. I have a Sony DVP-S500D and it plays cd-rs just fine (if burned at 1x with the cheap brand I use and 2x or higher with TDK or Verbatim).

A big resounding NO!! I, along with a friend, went shopping for a Sony VCD Discman. We bought along a wedding video I put on VCD using silver CTX CD-R media to be used for testing. It played well on a D- 7000 VCD Discman, which is what we bought. While there a new 725 was on display and we tried the CD-R on it. It kept telling "NO DISC". Too bad because the 725 had Dolby digital decoder built-in and component outputs. On close look at the front, there was no "dual- discrete optical pickup" on the tray itself that was familiar with older models, like the predecessor of 725 which was the DVP-S715 (and could play CD-R). It continues to amaze us up to this minute why Sony would backtrack and regress to this state. Anyone out there have any ideas to and about this mystery??? Could Sony be doing this as a way to prevent piracy??? The paradox is Philips/Marantz has continued to put out models that can read CD-R, and Pioneer is actively promoting the fact that its latest DVD set-tops have "twin-wave lasers", and are therefore able to read CD-R.

Why would Sony pull the dual descreet pickups? Easy... they want MiniDisc to rule the recordable optical market, and what better way than to take a cheap shot at CD-R.

I Think yes...use CD-r PRINCO Let me know your results, with me it works

I own a DVP-S725D since March '99 (PAL version) and after a lot of testing I'm sure it only reads RD-RW. Any colour of CD-R does not function, either for music or VCD. Now I produce VCD on CD-RW that function OK.

lead data cdr-80 min/700 - 730 mb silver blue professional Princo cdr-74 74 min/650 mb 2x 4x 6x 8x 12x EMTEC/BASF cdrw - 74 74 min/650 mb 1x 4x Tested and all's ok

-- JC (, November 12, 2001.

I've made the very same experiences. PRINCO's CD-R is okay but also every CD-RW I've tried - they are all fine :-) I've also tested many CD-R's without success :-(

I hope you can help.. I don't know if I can post a question here but......I have the sony s725d player. It is chipped but will not play the RCE disks. Does anyone know how to change the regions on the machine? Or any cracks to play the disks? Please help

thanks Antonio

It plays Princo CD-R, also plays XVCD and MPEG 2 if you demultiplex, and multiplex again as VCD and burn as VCD.

I to have a DVP s725D, I have an interesting theory........The PS2 when designed had the laser tuned so it would just read the oridginal disks, some of the PS2's about skip slightly when playing copies. I have heard that the laser can be re-tuned to pickup the disks alot easier. This is due to copies having less reflectability than an oridginal.

If the player can play some copies it should in theory play others the only difference between the cdr's is the reflectivity of the media and type of meterial used to produce them.

Has anybody else heard the same...........can anyone get hold of a service manual or circuit diagram for the dvd player, I like to tinker in electronics might be worth a look.

As much as I dislike replying to ancient threads...

You can't 'retune' a laser. The wavelength is determined by the bias material. What you're suggesting, Paul, is akin to changing your Trabant into a Mercedes by putting better petrol in the tank. :)

Better DVD players will have two lasers, which operate at different wavelengths-- one for DVD and another for VCD, CDR, CDRW, etc.


-- No One (, September 25, 2002.

I have a Sony Playstation, one of the first models, and in it I'm able to tune the laser to better read CD-R:s. I don't have a modchip or something like that, but I burn music I've composed on CD:s and my Playstation had problems playing them. Inside there are two "screws" that I found guides to on the Internet how to tune them. By adjusting these my Playstation plays my CD-R:s like a dream.

Then for the Sony DVP-S725D. I have just bought one and I have been trying CD-R's in it. None of them have worked. I have tried the following CD-R's and CD-RW's: Kodak CD-R Ultima 80 700 MB, Maxell CD-R 80 XL-S 700 MB, TDK CD-R80 Reflex X 700 MB, Traxdata CD-R TXS1280 700 MB, HP CD-R C800A 700 MB, Platinum CD-R 700 MB, Maxell CD-RW 650 MB, Memorex CD-RW 700 MB. None of these have worked. I have burned all of these at 4x speed, cause the software wont give me lower speeds. Maybe 1x speed would do some difference here.

Because I'm naturally skeptical, I looked up the 'tuning' instructions on the net.

From the instructions and the description of for what one needs to listen during 'tuning' it appears that the pots in question change the focus of the laser via moving the laser with respect to the plane of the disk. It also sounds if Sony removed this ability from later Playstations.

I doubt (but may be wrong) that Sony includes such 'tuning' pots on their DVD players.

Sony has a somewhat quixotic vision of trying to force consumers into purchasing proprietary devices (witness Betamax and Minidisk) and going so far as seeming to deliberately prevent the use of competing less-expensive technologies with its devices.

IMHO, they've also seemed to pay for the development of products such as Minidisk and Playstation by sucking the quality out of their consumer products-- they may be reliable, but I don't think they sound or look as good as their price commands.

While I have purchased Sony's consumer products in the past, I no longer even consider them at purchase time.

(*disclaimer: please note that this post does not refer to Sony's Pro line of anything, which are, almost sans reservation, absolutely brilliant.)

Good News for everybody with a DVP-s725d player. Princo 48x CD-r works out at DVP-s725d
