Home | Computers & Technology | Gadgets And Gizmos In order to understand DVD recorders, you need to understand disc formats. The five single-layer recordable formats are DVD+R/RW, DVD-R/RW, and DVD-RAM. Some DVD recorders are capable of handling all the five formats, while other recorders aren’t. The write once formats including DVD-R and DVD+R and are widely compatible with most DVD players and DVD-ROM drives. There are rewritable disc formats like DVD-RW and DVD+RW. Most players can playback these rewritable formats, but they are not as compatible as write once formats. Some DVD recorders support DVD-R DL (dual layer format) or DVD+R DL (double layer) formats. With twice the capacity of standard DVDs, these formats record video at the highest bit rates possible delivering maximum picture quality. Usually DVD recorder manufacturers call this high-quality recording mode ‘XP’ or ‘1 hour mode’, as you can record one hour programmes onto a write-once format. If your recorder has the ability to play dual-layer or double-layer media, then XP mode can provide two hours of high-quality video on one disc. DVD-RAM is a rewritable format with advanced random-access capability. It allows on-disc recording and playback at the same time. However, only some players are capable of playing back DVD-RAM. Types of DVD Recorders DVD recorders are divided into different types, such as straight DVD recorders, DVD recorders with built-in hard drives, and a combination unit of DVD and VHS recorders. DVD recorders function similarly to a VCR, using discs instead of tapes. A DVD recorder with a built-in hard drive provides more disc space through the Personal Video Recorder (PVR) function. This recorder allows recording extensive content onto the hard drive and then selecting your favourite programme and transferring it to a DVD. Another type of recorder available is a DVD recorder with VHS. This is an easy way of copying your favourite videotapes onto DVDs. Programs and Features Explained Most DVD recorders support a feature called VCR Plus to increase programming. Some hard drive recorders come with electronic program guides or EPG that enable point-and-click recording. Almost all DVD recorders come with manual programming, while some offer a quick, one-touch recording option. If you want to record from a satellite or a cable channel that requires a box on top of the set, your recorder should be capable of controlling the receiver or cable box. Recording time is another important factor to consider. A DVD recorder has the capacity to increase the amount of data compression by offering multiple compression techniques with varying recording times of 1 to 8 hours. Some recorders have automatic time setting that adjusts recording times and available disc space. In addition to recording and playing back DVDs, all players can handle CD audio and other disc types including VCD, MP3, WMA CD, JPEG CD, and DivX. Some DVD recorders even have memory card slots for displaying video. Although you only need a Scart socket for connections, a component video output and input are best for highest picture quality, particularly if your recorder supports progressive scan. On a high definition TV, recorders work well with HDMI output for improved image quality. The DV input assures maximum video and audio quality when the video is recorded from a digital camcorder, set top box, or a satellite receiver with FireWire port. Conclusion DVD recorders provide considerable convenience in recording your favourite movies on a single disc. With different formats and features, DVD recorders deliver vastly improved image and audio quality in comparison with VCRs. As a result, DVD recorders will almost certainly replace VCRs in most households. When considering a DVD recorder, think carefully about the disk formats you need supported. This is particularly important if you plan to share disks with friends and family or have a pre-existing collection. Also consider connectivity with your current and any planned equipment. There is nothing more frustrating than buying a device only to replace it three months later because it doesn’t support the HDMI input / output needed by your shiny new plasma TV!
