Why my DVD will not play?

[Forest1227]

I created many DVD-R's before and never have problem. Recently, I suddenly started to have problems: the DVD-R's I burned cannot be played either on my computer or on my DVD player, even though the program says "your DVD was completed successfully". I did not change the program. The same computer can still burn playable CD's. The DVD player can still play my DVD-R's made before the problem started. I suspect the discs were not finalized since I cannot see the burned tracks on the new DVD's; they are all shiny like the blank discs. What is wrong here?

When you burned your disk, did you use a different kind if disk than you usually would?

Usually, a new kind of disk would not be read due to old technologies.

Hope this has helped mate.

If its an old burner, replace it.

I am still burning DVD-R, nothing new.

I might try that if there is no obvious cause identified. But I am also speculating on the possibility of corrupted window files due to updates or malwares.

Run a virus scan with Avast and Malwarebytes

I have confirmed it's the problem of the DVD writer. Thank you all.
