A60 dvd multi recorder rw

You said in your post, "The DVD will be under My Computer, but I am unable to play/watch it."

You will be unable to play any DVD that is located under your computer! Besides, with your computer sitting on your DVD, you are very likely to scratch it! Better start putting DVD's in a DVD tray, or put it away in a sleeve or something similar to protect them from getting scratched!

check that is not a dirty lens problem, start using a lens cleaner disk

No you cannot record music to a DVD-RW. You must use CD-R media to record music as CD players cannot read DVDs. However you can burn the music to the DVD if you plan on using a DVD player to play the music. I beleive some recording hardware does allow you to use DVD's, but most use CD-R media or digital media such as a hard drive or flash media.

According to the user manual, the following DVD media you can record with this unit are:

RECORDING: TYPES OF DISCS YOU CAN USE FOR RECORDING

DVD+R 2.4x, 4x, or 8x ONLY; DVD+RW 2.4x and 4x ONLY.

NOTES:
It is NOT possible to record on CD-R or CD-RW discs.
IMPORTANT: It is NOT possible to record content that is copy-protected. This is usually true for most pre-recorded DVD discs and most pre-recorded VHS tapes.

PLAYBACK: TYPES OF DISCS YOU CAN PLAY

DVD discs - DVD movie discs (DVD-ROM); DVD+R; DVD+RW; DVD-RW (must be recorded using video mode or VM); DVD-R (must be recorded using video mode or VM and must be finalized).
CDs (Audio CDs, CD-R, CD-RW) - Audio CDs contain musical or sound content only. mp3 discs are CDs (CD-R or CD-RW)
that contain mp3 files. This product also plays CDs that contain JPEG files and Multisession CDs.
Video CD (VCD) and Super Video CD (S-VCD) discs - Like DVD video discs, VCDs contain picture and sound content. The difference is the amount of information that can be stored on the disc.
VCDs typically have lower picture and sound quality than DVD discs.
Super Video CDs (S-VCDs) can be used to record up to 70 minutes of digital sound and video, with MPEG-2 standard video and MPEG-1 standard audio-but you must use DVD+R or DVD+RW discs to record on your DVD/VCR not S-VCDs.
Additionally, S-VCD disc compatibility is dependent on which MPEG coding software, disc design software, and disc writer software are used; and the discs themselves.

(The above information is extracted from the user manual for this particular model and is a guide only)

I find it very strange that the user manual does not provide any information about DVD-R recording since this is a DVD recorder. I guess you could try those types of discs in it, otherwise it will playback finalised DVD-R discs recorded/burned in another machine.

I assume you have the original manual for this unit. If not, you may be able to download it free from various sites. (retrevo may have it but they may ask you for email address prior to downloading)

I hope the above information helps a tiny bit with regard to DVD formats for this unit.

You can't, that is the maximum for a CD-R or a CD+R = approx 700Mb capacity.
DVD-R and DVD+R have a capacity of 4.5Gb
Depending upon the type of data files you want to burn, there are compression techniques you and apply and then burn them to a CD.
For example you can convert CDs to mp3 music files and burn them onto a CD-+R disk. You can fit 12 to 16 CDs albums in mp3 format on a single CD-+R disc, but your CD player needs to be a MP3 player to play these music files.

Hi,
Does it do with original DVD or copied DVD ?.
if the original one works fine but the others not, your DVD may not capable of playing copy -R/RW discs..even though your DVD specs says: Plays DVD-Video, video-mode DVD-R/RW and DVD+R/RW, CD-R/CD-RW, MP3 CD, Kodak Picture CD, and JPEG image CDs, sometimes this happens due to bad recording of DVD .Try to use better recorded DVD or if possible use the original ones..
Thanks in advance for rating me..Regards

Are you sure that you have the file type associated in your Windows operating system to a Music player like Windows Media or iTunes? This may be the most common reason that music CDs won't play.

Probably a codec problem on the notebook. rather than a drive problem. Try a 3rd party media player such as Real Player or Quicktime

Try updating the firmware for it.

I had something similar to this happen to my desktop. I read somewhere that are are 2 laser in the drive. One to read dvds and other to read cds. Your dvd laser may be fried.
