So what exactly is a DVD recorder? Why would anyone want one? Essentially a DVD recorder is exactly like a VCR, except it uses DVD discs instead of VHS tapes. You can record any video or audio onto a DVD disc, and play it back later. Here are the advantages of a DVD recorder over a VCR:
Here are the disadvantages of a DVD recorder compared to a VCR:
So essentially a DVD recorder is better and cooler than a VCR, and also more expensive, as benefits a new technology. But it fills the same niche. It is worth mentioning, a DVD recorder is also a player. The Sharp in particular is a jack of all discs, it can play:
I want to dwell on the quality factor once more. Because of the price point and intended audience, DVD recorders are also the best quality DVD players you can find, with progressive scan video capability, component and SVideo output, fiberoptic digital audio, and full support for multichannel audio like Dolby Digital and DTS. You don't have to spend $600 to get a top-of-the-line DVD player, but if you spend that much to get a DVD recorder, it's nice to know you get a great player as part of the deal. Before I leave the "why would anyone want one" answer, let me tell you why I wanted one. Just one reason - to back up video I'd recorded on my Tivo. I'm a big-time Tivo user, and I record sports events and movies all the time. I've expanded my Tivo's recording capacity to 130 hours by adding a hard drive (about 40 hours at top quality), but that's still finite. I wanted a way to back-up video I'd previously recorded without suffering the poor quality of VHS. Recording to DVD fills the bill perfectly.
Well, no. There's really only one. Okay, okay, there are really two. Here's the story. There are two goals of recording DVDs: 1) to be able to play them back on the machine you recorded them on, and 2) to be able to play them back on a "garden variety" DVD player, like all your friends have. There are two DVD standards and they both do (1) and (2). The only thing they don't do is play on each other's recorders. The two standards are called DVD-R and DVD+R. That's right, the difference is that one has a dash between DVD and R, and one has a plus. { Who thinks of these things, anyway? } So, to recap, if you have a DVD-R recorder, your discs can be played on any DVD-R recorder and they can be played on "garden variety" DVD players. If you have a DVD+R recorder, your discs can be played on any DVD+R recorder and on any "garden variety" DVD player. You cannot play DVD-R discs on a DVD+R recorder, nor DVD+R discs on a DVD-R recorder. Okay, got that? Excellent! I should also mention that both standards support two kinds of discs. The first kind of disc can only be written once - after that it is read-only. These discs are called DVD-R or DVD+R. The second kind of disc can be erased and rewritten as many times as you like. These discs are called DVD-RW or DVD+RW. Why use the read-once versions? Well, the media for DVD-R / DVD+R are slightly less expensive than the media for DVD-RW / DVD+RW, about $4 per disc instead of $5 per disc. And, sometimes you really don't want something to be erased, so with DVD-R / DVD+R you can be sure that it can't be overwritten. The Sharp recorder is a DVD-R type device. They seem to be slightly more popular than the DVD+R devices, but as noted above it really doesn't matter. Perhaps someday one of the standards will "win", or there will be a new third standard which incorporates both, but that day seems pretty far off at the moment. Both standards allow you to record 4.7GB of data on a disc. This is enough for 2 hours of really high-quality video ("DVD quality"), or 4 hours of very good quality video ("SVideo quality"), or 6 hours of okay but not great video ("broadcast quality").
There are basically two ways to record video on a DVD. First, you can record it the same way as prerecorded DVDs, a format known as "V" (for video). If you record this way your discs will be 100% compatible with all DVD players. V-mode discs can have new data appended, but you cannot delete anything already on the disc. This is the only format supported by DVD-R media. If you have DVD-RW media you can erase the whole thing and start over. Second, if you have DVD-RW media you can record video in a format known as "VR". This format is much like a computer disc, you can add, edit, and delete content at will. However, VR-mode discs cannot be played back in "garden variety" DVD players, they can only be played back by your recorder (or another DVD-R recorder). So you trade the flexibility of editing with incompatibility. Here's a table which summarizes things...
As mentioned, the main reason I wanted a DVD recorder was to back up shows from my Tivo. I am going to be backing them up onto DVD-R media in V-mode, so they can be watched on any DVD player anywhere...
You got it. I've been checking out DVD recorders from Philips and Panasonic, and Sony is rumored to be hatching one. But when Sharp announced their recorder it seemed to combine all the features of all the others with a better price, so I jumped on it. By the way, this is definitely the leading edge of a new consumer product category, and prices are going to keep falling. So if $600 seems like too much, just wait. One thing I didn't know about the Sharp before I bought it but really appreciate now that I did is that it has an excellent manual. Really. It does not appear to be written in Japanese with English words, or use funky tables, or have diagrams that don't make sense. It just takes you right through using the device. And it starts simple and works up, so if all you want to do is put in a disc and press RECORD, you can. On the other hand if you want to fully edit your recorded video, you can do that too, and the manual explains how. Like most consumer electronics, the machine is driven by a remote control. A front-panel display tells you what's going on, but this is basically fluff; the machine has a great on-TV display which is what you'll find yourself using all the time. The remote is well organized and reasonably easy to use. Crucially, the battery door is solidly attached and doesn't seem like it will fall off any time soon. { If you don't think this is important, you obviously don't have as many remote controls as I do - or as many unattached battery doors. } Connecting the device is reasonably straightforward. It works like a VCR; you put it between your broadcast signal source (cable, satellite, etc.) and your TV. If you have a Dolby Digital receiver, you put the DVD recorder after the source and before the receiver, which in turn drives your TV and your speakers. The Sharp has a fiberoptic digital link for audio if you have a receiver which support this. I have to say the sound was excellent; I tried The Matrix (of course, the standard system-test DVD!), and also some audio CDs as well as some CDs with MP3s, and it sounded great.
Another nice feature of the Sharp is a front-panel connection for a video camera. The Sharp accepts standard coaxial video input, but it also supports DV input directly. if you have a camera with a DV output this is a terrific way to capture the video from the camera and put it on a DVD. The DVD recorder can even control the camera through the DV link, which makes editing even cooler. I don't have a camera with DV output (yet!) so I didn't try this, but if you do this might be worth the price of admission all by itself.
Like a VCR, the Sharp DVD recorder can be programmed to record particular channels at particular times. It supports VCR+ codes if you are a fan of them; I guess it does make recording easier. { I do all my recording on the Tivo, of course, so I am not going to use the DVD recorder's timer at all, but for many people this will be quite important. } I mentioned editing video earlier, and this brings me to the most complex feature of the recorder which many people may never use. The editing feature is only available with DVD-RW media recorded in the VR-mode. (If you record in V-mode you can append new titles to a disc and do some really limited editing like setting title names, but that's about it.) If you're in VR-mode you can create "playlists", which are essentially like the menus you see on prerecorded DVDs. You can edit start and stop points, rearrange and rename titles, pick the still image you want to be displayed for a title, and so on. All using pretty intuitive commands from the remote.
As a final test, I transferred a basketball game; the Lakers beating the Timberwolves. { Great game, by the way. } I simply recorded it as I watched the game using the Tivo. Since I routinely fast-forward through the commercials, the DVD recording has the fast-forwarding on it. When I paused the Tivo I paused the recorder as well. In this mode it is possible to end up with a commercial-less recording without doing any editing; just record as you watch the first time. So that's the scoop. I'm pretty happy with the Sharp DVD recorder, so far it is exceeding all my expectations. Of course, someday someone will build a Tivo with a DVD recorder in the same box...
