My goal, in the short space this article allows, will be to tell you how to upgrade from a CD-ROM, to a DVD burner.
First, unplug your computer, and disconnect all cables leading to the keyboard, mouse, printer, and monitor. Remove the computer's side panel.
Before reaching inside the computer, discharge your body's static electricity by touching metal. If you have one, use an anti-static strap that you can attach to your wrist, grounding the other end to an outlet.
Now, look at the back of your CD-ROM. You will see three cables connected to it. There will be a small audio cable, a large ribbon cable, and a power cable.
Unplug these carefully. The ribbon cable, and the power cable will be especially tight.
With the cables unplugged, now turn your attention to the sides of the CD-ROM. You will notice it is held in by two screws on each side. Remove the screws.
Warning: please do not use a magnetic screwdriver while working on a computer. Remember, your computer stores data magnetically. Think of the mischief it could cause.
After the screws are removed, slide the CD-ROM out the front of the case.
Note that on the back of the CD-ROM is a rectangle containing six pins. Two of these pins will be jumpered together. Directly above the jumper will be the letters "CS", "SL", or "MA". Remember this setting!
Take your new DVD burner, and look on the back of it for that jumper. Put the jumper in exactly the same setting as on the back of the old CD-ROM.
If, for instance, it was underneath the letters "MA", then set the jumper to "MA" on your new DVD burner.
These letters "MA" stand for Master, meaning it is the master device on the ribbon cable. "SL" means Slave, and "CS" stands for Cable Select.
Slide the DVD burner into the front of the case, getting it flush with the front surface. Attach it to the chassis, using the two screws on each side that we removed earlier.
Plug in the audio cable, the ribbon cable, and the power cable. The power cable is keyed so it can only be plugged in one way, and the ribbon cable port has a pin missing that corresponds to a blank spot in the plug, so these are easy to get in right. The audio cable is trickier. You must turn it so the white wire is pointed toward the ribbon cable.
Put the side panel back on and reconnect the monitor, keyboard, mouse, and any other devices you may have. Hook up the power cable, and boot up.
Any Windows operating system 98SE or later will recognize your new equipment and load the appropriate drivers.
You are ready to burn DVD's!

The DVD Decision
CD-ROM Drives triggered a revolution in the computer industry, but the only real change we’ve seen since their arrival is increased speeds. And speed only matters if you’re transferring vast quantities of data.
If you’re listening to music, a 4X drive is going to do as good a job as any other (except, perhaps, for a little digital re-sampling or searching between tracks). In fact, high speed disks can – due to spin up time – even slow down the transfer rate in the case of small files.
The only other interesting development in CD-ROM technology is that a number of manufacturers have attempted to make larger capacity disks, although most recorders and the majority of recording software don’t support them anyway. The result is that there is space for a new form of media, and that happens to be DVD. Isn’t DVD meant to be about movies and stuff? Yes, but there’s a lot more to DVD than movies.
For starters, there’s the issue of capacity. A DVD disc can hold 4.7GB of data. But this is just a drop in a much bigger ocean. DVD discs can also be dual-layered and double sided, which means that they can store even more data on a single disc. Indeed, you can store an impressive 17GB of data on a dual layered and double sided disc, blowing the average CD-ROM right out of the water.
Of course, you’ve already established vast collections of music and data on CD-ROM and you don’t want to throw them all out in the move to DVD. Fortunately – and this is one of the key strengths of DVD technology – all DVD drives are backward compatible, so you can still play your CDs and access your data on CD-ROM while using a DVD-ROM drive. This is critical to the DVD drive’s success, and without it, the DVD would simply be yet another media form. But it’s not, and if you ignore it you could find yourself left behind.
This all sounds like a worthwhile change, but DVD speeds also seem to be much slower than CD-ROM drive speeds. If you can store such large amounts of data, surely you’ll need faster drives? The problem is that this is much like comparing apples and oranges. Because DVD discs have a much bigger capacity, the tracks are placed much closer together so more information is read over a shorter space across the disc.
Furthermore, DVD drives spin a lot faster than CD-ROM drives; a 1X DVD drive spins at about the same speed as a 3X CD-ROM drive. With CD-ROM discs the tracks are further apart, so the DVD drive can increase its reading speed…often significantly. The result is that the speeds used in these two technologies are not entirely comparable, although there obviously is a relationship between the two.
For the DVD movie fanatic, speed is unlikely to make much difference. In fact, the only difference that you’re likely to notice watching a DVD movie on a faster DVD-ROM drive are smoother scanning through the movie and faster searching.
There are a number of other factors that are worth discussing, most notably the drive itself. Unlike a set top or standalone DVD player, a DVD drive can not, on its own, play DVD movies. To do this, you need an MPEG-2 decoder of some sort. Until recently, the most common way of doing this was to use a decoder card and DVD player software.
This is changing, however, and many of the more up-market graphics cards now support DVD and are capable of performing MPEG-2 decryption (with the help of specialized software). So, you may well discover that your graphics card or DVD drive comes with a ‘soft’ DVD player. Whatever the case may be, ‘soft’ DVD players use system resources, so count on needing a fair amount of RAM and a reasonable processor.
More importantly, you’ll need a good sound card and a graphics card with a fair amount of dedicated memory. At least 16MB. You may discover that you can use your DVD drive without a decoder card, but you will miss out some of the features that a good decoder card can offer.
So what’s in a decoder card? Well, if you don’t have a DVD compatible graphics card, a decoder card is essential. Furthermore, if you don’t have a graphics card that can provide high resolution graphics, a decoder card will ensure that you can still watch your movies at high resolution and in full 32-bit color.
With a good DAC (Digital to Analogue converter) on the card you can expect sharp, clear images at high refresh rates. The dedicated hardware also frees up resources, taking the load off your processor, RAM, and graphics card.

how to fix dvd/cd-rom driver missing or corrupt?
my dvd/cd-rom has a yellow triangle by it and says the driver is missing or corrupt. i have an acer.
this the info for my driver
HL-DT-ST DVD+-RW GSA-H21N ATA Device
i already went to devie manager and tried to update my drive but it said that my driver was up to date
If you have an Acer there is another program that you can download from the disk. Its called NTI and it should be on one of the disks that you got with your computer. You will need to register it with the company, but when they ask how you got the program, tell them that it was included with your computer.That way you can use the program for free and you will be able to recieve help.Plus you will also be able to get updates for it which will be downloaded automatically. This program is a lot better than the one installed on the computer. If you need more help email me. twentyeight7@yahoo.ca

HENDERSON, Nev. - Days before hosting an intensive health care summit with both Republicans and Democrats, President Barack Obama made a fervent push for his overhaul, calling it critical not just for the millions without insurance but for the entire country's economic well-being.
