My Dvds used to play fine untill i tried to play a very badly scratched Dvd, i dont know if this the cause but now when i try to play dvds and cds the sound is very crackly and jumpy. What could have caused this and how do i fix it?

Hello, Bloody_dark -

Often those who rent DVDs or borrow them from the local public library mishandle them and do not know how to handle them properly.

From your question, it seems the DVDs are either scratched or dirty (possibly with food residue.)

This website gives step-by-step instructions on how to clean the readable side of a DVD:
https://www.wikihow.com/Clean-a-DVD

If, after cleaning, the DVD still is grainy, patchy, skipping, etc., it is probably scratched.

What I do when I have a rented or public library DVD which is scratched, I return it with a "sticky note" attached to the DVD box stating it is scratched and that I properly cleaned residue from the readable side of the disc, so that the rental business or the library staff will know that the DVD is damaged and can choose to replace it.

There are ways to remove scratches from DVDs, but I do not recommend anyone try those steps if they do not own the DVDs themselves.

Note: I am a librarian by profession and have seen firsthand how people mishandle DVDs. I'm from the 45-rpm and 33-rpm vinyl record generation. We learned how to properly handle those vinyl records so as not to scratch them. Bottom line: We were taught to only handle the vinyl records (and subsequent CDs and DVDs) by their outer edges. For CDs and DVDs, they can be held between the thumb and forefinger, along the inside and outside edges.

most sony CD and DVD players have a digital signature design to play CDs and DVDs that are original and licensed. some CDs or DVDs dont work since the player does not recognize or scan any digital signature embedded in the CD or a DVD. 2nd, lens problem causes most players not to read CDs nor DVDs. you can try to buy CD or DVD lens cleaners to have your lens cleaned.

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.

Try re-installing your the driver for your dvd rom. Then try to put different dvds and check if it can read from your drive. If problem remains, I suspected it's your dvd rom is faulty

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.

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.
