Why does dvd-rw keeps reformatting in video recorder?

A DVD-RW may keep reformatting in a video recorder due to compatibility issues with the recorder's firmware or settings. If the disc is not finalized or is formatted in a way that the recorder cannot read, it may prompt reformatting. Additionally, using a disc that has been previously recorded on another device without proper finalization can lead to this issue. Lastly, the disc itself may be damaged or nearing the end of its lifespan, causing read/write errors.
