DVD recorders have a number of distinct advantages over previous methods of recording from your TV, namely using VHS recorders, which they are commonly compared with. However, you may find you like using a DVD recorder for your favourite movies and shows, rather than a digital video recorder (DVR --sometimes known as a PVR for personal video recorder, like TiVo and other devices) which records onto a hard drives.
One of the biggest advantages DVD recorders have over VHS recorders is that the quality of the recording is superior. DVD recorders produce digital copies whereas VHS tapes do only analogue copies. DVD recorders provide a much sharper image than VHS recorders. However, even when recording to a DVR, you often will find that recordings directly made to a DVD recorder are superior. That's because DVRs record to a hard drive. Recording to hard drives often requires a sacrifice of some quality in order to save space on the drive. In the case of recording to a DVD, since there is a single standard for DVD, the quality of recordings are the same across the spectrum.
More Choices and Usage Options
Another advantage DVD recorders have over VHS recorders (though not necessarily DVRs), is the range of options that DVD recorders offer. Often, you can create new menus on DVD recorders. You can also often choose to include the subtitles as an option. DVD recorders also offer an advantage in the amount of material that can be recorded. Traditional DVDs can record roughly the same amount of time as a VHS tape (about 2 hours). However, dual layer DVDs can record double that amount without degrading quality, a trick that VHS tapes are incapable of. Also, DVDs can be double sided, offering double the amount of recording time.
For quality digital recordings, you can take a DVD practically anywhere. The hardware required for viewing DVR recordings isn't as easily portable. When you record to a DVD, you gain the option to take the DVD anywhere and play it back on another DVD player. That's because virtually all DVD players can play recorded DVDs. Exclusively hard-drive based DVRs, such as those commonly offered by cable and satellite companies, while they have greater capacity also have a disadvantage. These machines lock you into watching the recording right there, on the machine they are stored on.
