It depends upon what type of data you want to copy onto a CD or DVD.
If you want to copy and play music in a CD player then it needs to be on a CD disc.
If you want to copy and play movie DVDs in a DVD player then it needs to be on a DVD disc.
If you want to backup data files then it can be on either CD or DVD discs (depending upon the amount of data to be stored on the disc - CD holds 700 Mb, single layer DVD holds 4.7 Gb, and dual layer DVD holds 8.5 Gb of data).
A DVD player can read both CDs and DVDs, but a CD player cannot read DVD discs.

I put in a blank or recorded disk ,and the screen message is " unknown disk", and ejects the disk. I have used different blank disks,with the same result. Seems it is not " reading" the disk. Probable...


are you sure the drive is a read-writer? some optical drives are read only. If its not a writer and you put a blank in, that is what it would do.

If you put a real and recorded disk in(not a copy) and it says unknown disk, the eye is dirty. Cleaning the drive will be the next step.

Burn project ejects blank DVD-r


If you are prompted to insert a CD/DVD blank disc into the Burner, you must have the proper UNUSED CD or DVD blank disk. You must use the SIZE disc that corresponds to the Size of the Data to be burned. A CD is 700 Megs thus anything greater than 700 Megs needs a larger disc such as a DVD that is 4.7 Gigs. If the data you are trying to copy to a disc is over 4.7G you need a Dual Layer DVD or BluRay that accepts 25Gigs.

What do + and _ signs mean on blank dvds


- RecordNow! can record only to the same disc type
it records from. For example, you can record a
DVD only to a DVD+R or DVD+RW disc, and you
can record a CD only to a CD-R or a CD-RW disc.
you were using DVD-R, so it won't work.


hope this helps

Trying to record to disc from VHS After recirding 8 copies, it now reads "Unknown disc, Please check disc" This is a Go-Video VR3845 Unit.


Hello,

I answered this question previously and the solution remains the same;

how long have you been using the player and has it ever accept blank DVD-R discs in the past.

The problem might be as a result of weak laser (lens) or the blank discs inserted might not be compatible with player.

When the laser(lens) of a player becomes weak, it will not be able to read blank discs. It only takes a very strong laser to read/accept blank discs. If it happens that the laser (lens) is the cause of the problem, then it means you will need to replace the laser (lens) to a brand new one to be able to read blank disc. Though the player might be playing DVD and CD, note that blank disc is stronger when it comes to reading from the laser (lens), it requires sharper laser. I hope you understand this.

So, insert a CD into the player and observe if it will play.If it plays, then its obvious that your laser is very weak.

Concerning the incompatibility issue, I hope you are aware that there are various kinds of empty DVD discs such as DVD +, DVD -, DVD RW. Try any of this empty DVD discs as one of them as to be compatible with this DVD recorder.

Amongst the two topics discussed above, one has to be the cause of the problem. So its up to you to figure out which is the cause of the problem.

I hope you understand the above....

I wish you good luck.

Cd not recording


Be sure to "finalize" the recorded cd before use in another cd player. Another thing is there are always a few bad discs in a spindle of blank discs... And sometimes you will get "check disc" or "bad disc" when a blank disc is inserted. I would be sure to use blank discs for audio use, not computer use, with your Yamaha.

You are probably inserting blank computer discs, eg 650 or 700mb rather than blank music CD-R or CD RW`s which this machine is designed to work with. The correct discs are labelled "music audio" or 80 minutes. You can only use these types of discs. Why? When these recorders first came out, it was a way of battling piracey in copying discs. I believe there is a "hack" to enable this player to use blank computer discs.

Recording from vhs to dvd


Direct copy VCR to DVD:
- Insert VHS tape you want to copy
- Insert a recordable DVD disc
- Press DVD copy button on front panel or remote control (to DVD).
- To stop recording press the stop button.

IMPORTANT: If attempting to copy copyrighted material the Samsung DVD-VR320 will detect the encoding and will not allow the copy to be made.
