DVD ROM I can ply Audio Cd, VCD, but not a dvd disc, what cause on it?

is resolutions pixel problem only on the dvd disks you burn?
you might have to save the dvd to a file first then burn it to a dvd
are you copyning from another dvd or from a saved file ??
you might be burning it as data
this might be a problem with the quality of the dvd disks you are using or might be the software you are using there are lots of free burning sofrware programs on the internet
this might be because you have not selected the option to burn an audio or data dvd or your burning software does not support dvd burning
there are plenty of free burning software programs on the internet

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.

Page 12 of the manual...

Just the CD discussion. DVD is above it on page 12...

CD [CD] [WMA] [MP3] [JPEG] [VCD]

≥This unit can play CD-R/RW recorded with the above formats. Close the sessions or finalize §2 the disc after recording.

≥ [CD] This unit is compatible with HDCD, but does not support the Peak Extend function (a function which expands the

dynamic range of high-level signals).

HDCD-encoded CDs sound better because they are encoded with 20 bits, as compared with 16 bits for all other CDs.

≥ [WMA] [MP3] [JPEG] This unit also plays HighMAT discs.

≥[WMA] This unit does not support Multiple Bit Rate (MBR: a file that contains the same content encoded at several
different bit rates).

§1 Includes single-sided, dual-layer discs.

§2 A process that allows play on compatible equipment.
≥ It may not be possible to play all the above-mentioned discs in some cases due to the type of disc or condition of the recording.

Discs that cannot be played

DVD-RW version 1.0, DVD-ROM, CD-ROM, CDV, CD-G, SACD,

DivX Video Discs and Photo CD, DVD-RAM that cannot be removed

from their cartridge, 2.6-GB and 5.2-GB DVD-RAM, and "Chaoji

VCD" available on the market including CVD, DVCD and SVCD that
do not conform to IEC62107.

All except the bluray ones.

Combo drives have 2 lasers inside of them. An IR laser to read CD/VCD and a red laser to read DVD. It sounds like your laser to read DVD discs is dirty or has developed a fault. A replacement drive would be your best option as they are now very cheap and it will resolve the issue quickly.
Hope this helps,

You can't burn a DVD movie using a COMBO drive or Compact disc rewriter, change your movie format from DVD to VCD and then try again, I recommend you use nero to make/edit movie and ImgBurn to make ISO image and burn it onto disc.

DVP3120 can play all DVD, VCD,MP3 and Audio CD and Support the below formats
Audio Video format NTSC & PAL
DVP3120 will play CD, CD-R/CD-RW, Video CD/SVCD, DVD, DVD-R/-RW, DVD+R/+RW, DVD-Video Discs as well as MP3-CD, MP3-DVD, WMA-CD discs and MP3, WMA and JPEG Files.

Let me know if this helps

You likely do not have a DVD-Rom. Check the front of the DVD and be sure that it says DVD-ROM on it. If it does not you may consider contacting Acer to upgrade it.

I have the same problem like you.one of the expert shared to me that my burner has faulted. I thing your problem is worse than mine cause I can still read cd rom vcd/ DVD files and movies. Just finfd new one that will give you quality output.
