    CD-RW works, CD-R does not

    I have tested some VCD video clips by burning them on CD-RW with an HP 9200i. They played just fine on TV using a Sony DVD player.
    So I burned the clips on a CD-R and created a coaster: the CD-R does not play in the Sony DVD player. "No disk" is the DVD player comment. Strangely enough, it plays well using the PC DVD and software. Go figure.

    I always thought that CD-RWs are more of a headache, now it is the other way round ;(

    The difference is often just a matter of reflectivity.

    CDRW's are mostly silver or silver-blue with 75-90% reflectivity.

    CDR's are often dyed darker colors (green, blue, black etc.) with only 50-60% reflectivity.

    Older DVD decks cannot "see" disks with 50-60% reflectivity. CDR compatable decks have more sensitive detectors.

      Doc,

      My CD-Rs are silver-silver.

      I am pretty sure that it also has to do with the burning software. As mentioned in another thread, I have not yet been able to burn successfully with Nero. I.e., even the CD-RW that plays well when burned with EZ CD does not play (is not recognized) when burned with Nero. Everything else the same.

        Nothing to do with the burning software assuming you've created each disk the same and they are in the correct VCD or SVCD format.

        Make an audio CD on each media. I predict the CD-RW will play in your DVD player, the CD-R one won't. Try them in your car or other audio CD player -- the situation will be reversed.

        "visible" color also has little to do with it. What counts is the albedo at the specific laser wavelength.

          Hapz,
          I have the same problem with VCD/XVCD on my Sony 725D. Actually, -IMHO- it's a matter of CD-R reflectivity ; so far i have tested many brands and the only one that played was a PRINCO silver/blue (marked x2x4x8). All tests were made using the same video-clip(TMPeng encoded, VBR quality 100), burning software was NERO 5.0.3.8 and the recorder was a YAMAHA 4416 (burning speed x4). However, lately i got a "NO DISK" message using a new PRINCO (x2x4x8x12 and i don't know if it's CD-R related or if it's the different mpeg encoding i used for(CBR 2500kbit)??? (still testing).
          I have never had problems with CD-RW disks.
          For user comments on CD-R compatibilty with DVDs have a look at http://www.vcdhelper.com/dvdplayers.php

          Which is the brand of the silver/silver CD-Rs that you use?

            Hi,


            Afraid it's nothing to do with burning software... the newer Sony DVD player won't play CDR's.

            It confused the hell out of me. I tested a CDR on a Sony 515 and it worked perfectly, but the newer ones... 525, etc aren't dual laser.

            http://www.vcdhelper.com/ is a site that deals with comaptibility problem of CDR's and DVD players.

            Regards,

            Nick.

              Ok, it seems that my Sony DVD player does not play CD-Rs ;( At least based on the vcdhelper list.

              I did some more testing, and here is what I came up with:

              Sony S570D (TV) Creative DVD (PC)
              w/ software DVD players
              (Power DVD & Matrox DVD)


              EZ CD CD-RW ok ok
              CD-R not recognized ok


              Nero CD-RW not recognized not recognized
              CD-R not recognized not recognized

              Click'N Burn
              CD-RW ok error message or no play
              CD-R not recognized error message or no play

              None of the CDs burned with Nero play. They are also not recognized by the OS, software players, or the Sony player Strangely enough so, all three burning software packages were able to list the seemingly correct track information. That applies also to the other non-playing CDs burned with the other packages.

              Looking at the results, I must conclude that software has an impact on the outcome. It is not just the CD material, or the DVD player.

              Why, is a different story.....

                Sorry, but the table did not come through the way it was intended ;(

                Sony S570D (TV) Creative DVD (PC)
                w/ software DVD players
                (Power DVD & Matrox DVD)


                EZ CD
                CD-RW ok ok
                CD-R not recognized ok


                Nero
                CD-RW not recognized not recognized
                CD-R not recognized not recognized

                Click'N Burn
                CD-RW ok error message or no play
                CD-R not recognized error message or no play

                    FYI, I got the Nero problem resolved. Nero finally came through with a suggestion that worked: "Set Disk at once."

                    At least now I can play SVCD with CD-RW

                    I am looking forward to see how this works in Europe next week. I created a set of VCDs and SVCDs in PAL.
