I watched a DVD earlier this morning, but suddenly, my player refuses to read DVDs. It reads CDs perfectly fine, but if I put a DVD into the tray, the player reads, "NoDisc.
" What can I do to fix this. I'm afraid that I no longer have the reciept! Help please.

Most likely the DVD laser lens is dirty. Unplug the CH-DVD 300 from the wall outlet, wait 5 minutes, then remove the top cover. Next, remove the rectangular metal plate which covers the area where the CD or DVD disc would be when in the player's tray. Underneath the rectangular plate you should see two small lenses. Gently clean these lenses using ear swabs moistened with isopropyl alcohol. Reassemble the CH-DVD 300 in the reverse order that you disassembled it, plug it back into power, and now it should read your DVD discs just fine.
Many times the drive itself is going bad and will stop recognizing dvds first and then eventually will quit reading cds. That would be my bet. I have replaced dvd drives that were doing the same thing and the problem was solved. If it is under warranty Dell will replace it for free. They may ask you to reload your OS first especially if you are dealing with India, but you can lie and say you already did that.
If the lens is clean (clean with cotton swab and alcohol), then the optics are failing. DVDs require more power and accuracy to be read than CDs. The ability to read CDs but not DVDs is usually a good indication that the optics are starting to fail.
This problem is down to failure of the laser and an only be solved by replacing it. Samsung are aware of this fault but will only offer a free replacement if the unit is still covered by it's warranty. They do offer a replacement service but charge £94 for it.
The optical lens is out of alignment. This is why it will read CDs which have much larger data pits that DVDs.
The unit should be able to read and playback CDs (both production and burned) and DVDs (both production and burned). If the optics are out of alignment and exceed their tolerances, the player will not read discs.
This is caused fromt he player being dropped or jarred.
This is not an easy fix for the home user. This is something that a qualified professional needs to correct.
Chances are, your DVD player uses one laser to read CDs, and a different laser to read DVDs (since Cds and DVDs are read at different wavelenghts of light). If the DVDs you're trying to watch work properly in other DVD players, it probably means that the DVD laser is dirty, damaged, or burned out. Though you can try cleaning the laser (use Google for suggestions on how to do this, or check the Audiovox website), you will most likely have to get the DVD player repaired, or buy a replacement.
Many of the newer CD/DVD players sold today use a single combination laser, which reads both CDs and DVDs, which means that when the laser fails, it will not work at all. Wish I had better news for you, but I guess that the only consolation you have is that your Audivox player still works with CDs...
In response to your jvc-a75r DVD player, sometimes the solution might be less complex than it may appear. Had the same problem with my Samsung s321,the machine refused to read DVD's but would play CD's no problem. Simply opened up the cover(usually)4-6 small screws, and found my dog's hair inside of the player covering the laser eye.Electrostatic ionization
attracts dust,etc. into the player remarkably well sometimes. Carefully used a cotton swap to remove debri. PLayerworked fine afterwards
