If your Rosen Piranha multimedia navigation head unit is not reading CDs and the DVD player is not working properly, there are a few things you can try:

1. Check the disc: Make sure the disc you are trying to play is clean and free from scratches or other damage. If the disc is dirty, clean it gently with a soft cloth.
2. Check the format: Make sure that the disc you are trying to play is compatible with the DVD player. The DVD player may not be able to read certain formats, such as Blu-ray discs.
3. Check the connection: Make sure that the cables connecting the DVD player to the head unit are properly connected and not damaged. Try disconnecting and reconnecting the cables to see if that resolves the issue.
4. Check for firmware updates: Check the manufacturer's website to see if there are any firmware updates available for your Rosen Piranha head unit. Updating the firmware may resolve any software-related issues that are causing the DVD player to malfunction.
5. Reset the head unit: Try resetting the head unit to its factory settings. This may resolve any software-related issues that are causing the DVD player to malfunction.

If none of these steps resolve the issue, it's possible that there is a problem with the DVD player itself. In that case, you may need to have it serviced or replaced by a qualified technician.

There are several possible reasons why your DVD player is not playing movies, but is playing CDs. Here are some steps you can take to try to fix the issue:

1. Clean the disc: Sometimes, a dirty or scratched disc can cause the "no disc" error message. Try cleaning the disc with a soft, lint-free cloth, wiping from the center outwards. Avoid using harsh chemicals or abrasives.
2. Clean the DVD player: A dirty lens or other components in the DVD player can also cause problems with reading discs. Try using a DVD lens cleaning kit to clean the lens, or open up the DVD player and carefully clean any visible dust or debris.
3. Check the disc format: Make sure that the movies you are trying to play are in a format that is compatible with your DVD player. Some players may not support certain file types, such as Blu-ray discs or region-specific DVDs.
4. Check the connections: Make sure that all cables and connections are securely plugged in and functioning properly. Try using a different cable or port if possible.
5. Reset the DVD player: Some DVD players have a reset button or option in the settings menu. Try resetting the player to its default settings and see if that resolves the issue.

If none of these steps work, it's possible that there may be a hardware issue with your DVD player, such as a malfunctioning laser or drive motor. In that case, it may be necessary to take the player to a repair shop or consider purchasing a new one.

Is that what you are finding?

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 were saying some? and not all the cds and dvds? it may be that those other discs are unreadable anymore caused by scratches, marks, or the like. if other discs can be read then the player is all good. also check what file format you are trying to play. it may also be that the file format you are playing is not compatible with the program you are using to play it with like windows media player, media classic, etc.

CDs and DVDs don't need to be formatted, unless you're using a DVDRW (Rewritable) and want to erase what's on it. Regular CDs and DVDs are single-write onl, and don't need to be formatted before burning.

No Disk issues on device players like DVDs are caused by the following problems

Dirty Play Heads (Optical lens)
Bad CDs or scratched CDs on the surface
Non Compatible CD formats such as DVDs that are designed for some geographical regions and play formats
Also low electrical current is a major problem too

Your issue could reside amongst any of these problems

Check your DVD compactible play formats if its compactible with the CD you want to play.

If its compactible, then I suggest you get a CD Cleaner to clean to clean to Lens.

Also check your current output and if low, get a voltage stabilizer

Check the surface of the CD if its scratched and get a replacement.

Yes. Many burning apps (such as Nero) support the creation of Video-CDs, and most current DVD players support playing these Video-CDs.

I have seen this same thing on a laptop. DVD drives use two lasers. One for CD and one for DVD. As you noted CDs are just fine and so is that laser. Although I believe the DVD laser is intermittent. And it will work with some DVDs and not others. Yes I have seen this before. What will probably happen a few months down the road is it will stop reading all DVDs.

It isn't economical to replace the failing laser. It is far cheaper to just replace the whole DVD drive. Lasers are like light bulbs. Some seem to last forever and some seems to burn out right away. Generic DVD replacements will generally work, although the face plate might not fit.

Another option is to get an external DVD that plugs into the USB port. And those Slimline models are really small (same size as laptop CD/DVD drives) and you can use them on other computers too.

You might be able to convert them to DVD-Video format if you've got a DVD burner and the right software.

Another possible option would be converting them to a Video CD/Super Video CD if the DVD player can play Video CDs or Super Video CDs and you have a CD burner and software that can burn VCDs/SVCDs
