What is the difference between dvd and dvr

The difference lies in their formatting and how they read data on the disc. They're both mm in diameter and 1. DVDs, in general, are very data-sturdy and do not wear out with repeated use. A DVD movie, even after 10, viewings, will offer video reproduction identical to the day you bought it.

Different industry groups back each format. Your DVD drive determines which type of media to use, so make sure to match the type of disc you buy with what your DVD drive supports.

With the advent of internet streaming, some speculate that DVD media and hardware are heading for obsoletion. While demand for DVDs is clearly diminishing, they are still very much in use.

The amount of video the DVR can store depends on the size of this hard drive. Some models, however, connect to a home network to allow transfer to a computer. Users can play any of these discs in a compatible DVD player or computer. DVRs connect through the television signal and provide an onscreen guide for watching and recording TV. These guides can automatically find shows to record by name or time.
