any suggestions?

thanks

Most likely, your panasonic does not read cdr and cdr/w.
It should be in your manual.

You can burn a Music CD and see whether it also failed to play.

Many Sony and Panasonic DVD players does not not play cdr/w,
and SVCD. So you can like most people I know eneded up with
two DVD players.

DUDE Check DVD Players Compatability List,
Your DVD will not play CD-R's

don't commerical vcds use cdr?

Not first-rate (legit) commercial VCDs. They are pressed just like a commercial DVD.

can you explain more in detail of what you mean?

thanks

You will have to buy(or trade) a multi-read dvd player.If the manual
says it can play cd-r,r/w,mp3 it will play homemade vcd's.

thanks for all your help

I have the Apex AD 1500, plays nearly everything, I went through this 4 months ago, my Aiwa can't do squat, so I used the DVD Player Compatabilty list, I wanted the best bang for my buck, $86 for mine as compared to $200 for the Aiwa.

A commercial ( or press CD ) is a piece of plastic with a lot,..a lot
of laser machine holes in it.

A CDr or CDRW is coated with a die, that will chnage it's reflective angle
when a burn uses its laser to shine on it. These spots behaved like holes to a cd or dvd player reading laser.

A pressed CD or DVD is forever other than accidental destruction.
A CDR or CDRW's information will only last 3 to 7 years.

First off cd-r's proerly cared for will last mush longer than 7 years.

CD and DVD's are based on reflecting a laser off of a surface and depending on if the laser gets bounced back it reads a 1 or 0. DVD's take this a step further by using two layers, and the laser used can be focused on the first or second layer.

Commercial CD's and single layered DVD's use alunimum or gold as the reflection layer. Since these surfaces reflect almost anything almost any wavelength could be used and would work properly.

CD-R/RW use a DYE or chemical layer that changes it's reflection properties under specific conditions and they have a solid reflection layer. It's the DYE that determines if it reflects or not. Only specific wavelenghts can read the DYE layer. Some wavelengths will cut right through the chemical and some cannot penetrate the chemical resulting in the disk being read as all 0 ot all 1.

The problem occurs because the wavelength used for dual layered DVD's cannot normally read the DYE on CD-R/RW's. Commercial CD's are a freebie since it's the same materals as commercial single layered DVD's and they have to support that already.
