Final answer:
Compatibility issues and recording quality are the main problems that can occur when playing DVD-R discs on newer DVD drives. Technological shifts towards streaming and other formats like Blu-Ray also contribute to potential playback problems with DVD-R media.
Step-by-step explanation:
When recording on DVD-R discs and playing them back on newer DVD drives, several issues can occur. These issues include compatibility problems, where the newer drive may not properly recognize or play the media from a DVD-R. Additionally, as technology has improved, the newer drives are often optimized for formats like Blu-Ray, which may affect their ability to read DVD-Rs that have a different data structure.
DVD recording quality can also be a concern because if the DVD-R was not recorded correctly, with precise and accurately spaced pits, it could result in playback errors or data corruption. Also, changes in digital technology and the rise of streaming services have decreased the popularity and support for physical media, potentially leading to less rigorous testing and firmware updates for DVD-R compatibility across newer devices.
