There are a variety of different formats available for optical digital media storage today. There is the CD-ROM, HD-DVD, DVD-R's and HD-DVD-RW formats that are available. It can be a bit confusing, so you will want to know what the differences are between the different formats.The specifications for digital optical media formats are set by working groups. These working groups are made up of various engineers that represent manufacturers that are planning to build and sell their hardware. Usually every manufacturer has their own technology developed as well that they want to include. When they make sure that the technology that is preferred is in their specification, every device that is sold earns them a royalty payment. Since these devices sell millions each year, the royalties paid can add up to a great deal of money.Often there end up being format wars, since everyone wants to earn big money. One example of this is the format wars that occurred with BetaMax and VHD when the video cassette recorded emerged. Now days there is only one type of media that never had a format war, and that is the CD-ROM. Sony was able to hammer down most of the patents to the CD-ROM, which saved the format war problems from occurring.The first format for recordable DVD's was called the DVD-R, which came about soon after DVD's first became popular. Many wanted to develop a way that the DVD's would have both read and write capabilities, which led to the development of two different formats. The two formats are the DVD+RW and DVD-RW. The difference between them is very small, and it actually is mainly the controller chip that is different, but in the end there is very little difference between them. Eventually DVD-RW took a lead over the standard DVD-ROM drives; however, it is not a commanding lead. It was Phillips that was the first ever manufacturer to make a device that could read both of the RW formats for DVD, and they quickly became the standard device used.Once again the format wars began. High Definition television requires a great deal more information that you can put onto a single DVD, so the high definition DVD drive and media format needed to be developed. These special devices actually use lasers with shorter wavelengths, which actually puts smaller dots on the recording media. There are two different formats, which are called BlueRay and HD-DVD, and they are just now beginning to enter the market. No one is sure which one will have better success, but more than likely a company that makes a device capable of reading both will win over the market. While HD-DVD's are cheaper, the BLueRays offer more storage space and also have a longer shelf life as well.Usually it is the adult entertainment industry that picks out the winners in the market place. Currently they seem to be liking HD-DVDs for their formats of choice, and there are already people working on an HD-DVD-RW, and no doubt soon there will be another format war over this technology as well.

If so, you may be able to simple tap the front of the case to release the button. In some cases, you may have to remove the system unit cover to get the button to return to the out position.If you cannot stop the computer from rebooting by pressing the power button and releasing it, turn off the power switch in the back of the computer next to the power supply. If your power supply do not have a power switch, you will have to unplug the system from the wall outlet.This must be done as soon as possible so that the constant rebooting will not damage components such as the hard drive. Constant rebooting also have the danger of power surges that can further damage larger components such as the motherboard.Second you check your computers software by checking to be sure no virus or malware have not effected your hard drive. Virus and malware are small software that is downloaded along with other files that is designed to cause mischief.To remove any viruses and malware, use a anti-virus program that will search your hard drive and remove these file quickly.

BIOS stands for Basic Input Output System and is a small program designed to check all components for proper operation when the computer is turned on.If your BIOS has been changed or if youre not sure if its been changed, try to reset the BIOS settings to the default settings after you access the BIOS as the computer reboots.Once inside the BIOS, you should have the option to load your default settings, save the change, and reboot the computer.However, there are times when a continually rebooting computer will not allow you to access the BIOS. You can then reset the BIOS by removing the system unit cover and locating the jumper on a three pin header.You must consult your computer or motherboard manual to properly perform this procedure and it should be done as a last resort. Before making any changes to your BIOS, you should backup your BIOS if your computer reboots at long intervals.After checking your computers software for its rebooting problem, you must check to be sure hardware is not at fault. This problem may exist because one of your memory modules are unseated from its socket . Memory modules are long, narrow sticks that attach to the motherboard.Remove any static electricity from yourself, remove the system unit cover and check these memory modules to be sure they are secure. Check the connections to the hard drive and the connections leading from the power supply.Power supply connectors should be checked if youve done work inside your computer recently. Power Supplies are known to slowly fail and lead to rebooting problems. There is no way to check an ailing power supply and this should be considered the problem as a last resort.Following these steps will help you correct any computer that continually reboots itself. If no virus or malware is found, carefully and thoroughly check all connections. And if the problem still exist, the most likely cause would be the Power Supply.
One of the most common problems with a new home theater is the sound. The sound seems to be something that is very important to most people in regards to their home theater system. Most people would agree that the sound quality in a home theater is almost as important if not just as important as the video quality. If your home theater has the right sound, it could bring a movie right into your living room. If the sound quality is poor, it will remind you of watching black and white movies on your grandparents old console TV.There are many problems that can arise with the sound quality of your home theater. The following is not a troubleshooting guide, but more of a collection of tips on how to handle some sound quality problems. Some can be fixed with just minor adjustments of wiring or placement of speakers, but others may require a full replacement of certain components.Your first thought when your sound seems bad is that your speakers are bad. But before you rush out to the nearest electronics store and deplete your checking account, check these possible faults. The problem may not be in the speakers, but in the amp or the speaker wiring or connections. The first step would be to confirm that the speakers are properly connected at both ends.If the connections are correct, the next step is to determine if the problem lies in the speaker or the amplifier. Some of the less expensive home theater systems come with low end amps that tend to have more problems. People that have these systems in larger rooms tend to notice the problems faster because they are trying to push too much sound through the little amp and it causes more problems. To determine if it is the amplifier, hook up your speakers to your stereo. Stereos tend to have a more powerful amplifier and the speaker quality will likely improve. If the speaker quality does not improve, then it is likely your speakers at fault.Bad or old speaker wire or poor cabling could be a culprit to bad sound quality. Cheap quality cables are often included in home theater packages and can greatly reduce the sound quality in your system. This can be corrected by going to any electronics store and purchasing a higher quality speaker wire and ensuring that the corrections are made correctly.When you first experience sound quality problems with your home theater system, it is best to first check all of your connections. The connections and wiring are generally easier to check and cheaper to replace than a component itself. By ensuring that everything is connected properly and your amp has sufficient power, along with using high quality speaker wiring, you should have no problems getting the sound quality that you desire. Taking these simple precautions could result in much less headache in the end. Before you rush out and buy a new system, use these suggestions to make sure that your problem is really a problem and not just a misunderstanding.
