Key ConsiderationsRecordable DVD media is available in a number of different types, and the type that you choose will depend largely on the quantity, and type, of recording that you wish to perform. Disks given the designation "DVD+/-R" are the cheapest option, but can only be written once. This type of media can be useful for precious recordings that you intend to keep for posterity, but can also be quite wasteful, in terms of storage space. Disks designated "DVD+/-RW", on the other hand, can be rewritten many hundreds of times, and may be more appropriate for everyday recording, of television programmes, and the like. A further rewritable format exists, in the form of "DVD-RAM", although this is limited only to devices from certain manufacturers.
One of the possible limitations of DVD recording technology is the volume of data that can be recorded on a single, removable disk - perhaps an hour, or two, of video of the very highest quality - and, although this can be increased by reducing the recording quality, this does rather defeat the object of the exercise. An alternative solution is a hard disk drive DVD recorder, which allows recording to removable media, and to an integral, high-capacity, hard disk drive. Hard disk drive, or "HDD", DVD recorders are available with capacities of, perhaps, 80, or 160 GB, or more - sufficient for hundreds of hours of recording, depending on the chosen quality. HDD DVD recorders also often include useful additional features, such as something known as "live pause", or "time shift", which allows you to effectively pause, and rewind, live television programming.
Connectivity to, for example, an
LCD television set, or a digital surround sound system, may be an issue, and you should try to choose the best possible connections, in terms of quality, for both video and audio. If you are lucky enough to have one of the latest LCD ("Liquid Crystal Display"), or Plasma, television sets, you may be able to take advantage of highly efficient, all-digital connections, such as HDMI ("High Definition Multimedia Interface"). Similarly, many DVD players now feature coaxial, or optical, connections for digital audio, but, again, these obviously need to be compatible with the rest of your home entertainment system.
Conclusion
In addition to superb, digital, recording quality, DVD recorders allow previously recorded material, or free space, to be located quickly and easily, either from a user-friendly, on-screen menu, or by the recorder, itself. Despite inherently superior technology, DVD recorders actually have fewer moving parts than their VCR predecessors, and are therefore more reliable, and have a longer life span. DVD media, too, is must less susceptible to "wear and tear", and therefore degradation in quality, on repeated use.
