It sounds like you need to clean u'r lens in the DVD player. You can buy discs that will do that for you. Hope this helps

You are probably using incorrect disc formats in this DVD player; try DVD+RW if you must use re-writables, or DVD-R (finalised in a recorder or burned on a PC). I doubt this model supports DVD-RW, so the problem wouldn't be with the player; it would be the formats of the discs you use.

Don't use DVD-RW discs in this player if it does not support that format.

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.

U using DVD+R DVD disc?Not possible the DVD+R DVD disc to be reformat,it only can be burn and written data's into the disc only one time to the DVD+R disc.Are u using DVD+RW DVD this disc can be reformat,but DVD+RW DVD disc doesn't reformat by itself.It can't.The DVD+RW DVD disc data's only can be over written with new data's putting into it.

The user manual states:-

"The disc is not recognized in the DVD camcorder. The disc has been finalised in a camcorder manufactured by another company."

In plain English this means that the disc must never have been used in another DVD recording device.

It further states:-

"The supported discs are DVD-R, DVD-R DL, DVD-RW. Use a new disc."

Double check that you are using DVD-RW and not DVD+RW. They are NOT the same although many devices can use both types. Your camera only uses the DVD- standard and not the DVD+ discs.

If you are using new discs which have never previously been used and if the discs are of the correct type, then you have a faulty camera which will need repair or replacement.

I hope that my answer has been of assistance to you in fixing your problem or has helped you to decide what to do next. Please take a moment to rate my reply.

I not sure as to which type of Discs that you are refering to (ie DVD+R or DVD+RW). This player will only recognize 4x (max) DVD+RW and 8x (max) DVR+R discs. If the DVD+R Disc is 16x, the DVD recorder will not recognize it once you start to record. The player will read the blank Disc and give the impression that it will record on it. I have noticed that when a 16x speed Disc is in the Drive, The recordable hours for the disc seems to double. The normal 6 Hour recording length comes up as 12 Hours when you hit the info button. Since the 8x Speed (max) discs are not available any longer, I found it best to use the DVD+RW 4x Discs and make it compatible. I then copy the compatible DVD+RW disc to a 16X DVD+R disc using my computer DVD burner. The DVD+RW disc can then be erased so that it can be reused.

Here is a link to the manual:

It specifically lists disc types that you cannot use to record - it specifically states that you can't use DVD-R discs for recording on this unit. DVD+R or DVD+RW are the only disc types you can use for recording on this unit.

• Disc not loaded. Load a disc into the player, close the door and press PLAY.
• The disc used may be defective. The disc used may be defective, try another disc.
• The disc is placed improperly in the tray. Make sure the disc is properly placed and centered in the tray and if the disc has a label on one side, make sure the label is facing up.
• The disc is dirty. Use a soft cloth to clean the disc by wiping in a straight line from the center of the disc to the outside edge.
• Use of DualDisc or Flip Disc which does not meet the Compact Disc Digital Audio Standard. Some music labels have recently introduced the DualDisc for pre-recorded audio and video content. The DualDisc bonds DVD content on one side 'back-to-back' with digital audio content on the other side. However, the digital audio side does not meet the technical specifications specified in the Compact Disc Digital Audio Standard. For this Reason, DualDisc is not permitted to carry the CD logo. Philips DVD and CD players and disc drives fully comply with the CD specifications and therefore may not recognize the DualDisc. Attempting to use DualDisc may lead to playback problems or jamming in the slot loader or drive.
  The DVD video content on the DVD side of the DualDisc should play on Philips DVD players and DVD drives. However, Philips DVD players and drives do not support DVD Audio, and will not play any DVD Audio content present on the DVD side of a DualDisc. Philips will further investigate DualDisc and update this notice accordingly.
  

Here are some tips if your DVD player can't play DVD+ RW:

1. In order to play a DVD-R, DVD+R, or DVDRW disc, a DVD player must be compatible with those recording formats.
2. Ensure that the recording speed used to create the disc is supported by the DVD player.
3. This procedure assumes that the DVD-R, DVD+R, or DVDRW disc being used is not blank.
4. If additional model specific information is required to complete any of these steps, refer to the operating instructions provided with the player or recorder, or the help files of the computer software used to create the disc.
5. Ensure that the disc has been inserted into the player correctly.
6. Examine the DVD for fingerprints, smudges, or scratches and, if necessary, clean the disc using a soft dry cloth.
7. Ensure the disc has been properly created and finalized.
8. Ensure the DVD region code and format of the disc is compatible with the player.
9. Ensure the disc playback is not being restricted by parental control options.

If you still can't play that DVD on your DVD player, you can try to copy it to ISO file and play it on computer instead. Here I found a tutorial for help: How to Back Up DVD to ISO?
