If you have completed the setup process for your DVD, it will automatically be added to your online store. If you have not completed the setup process, you will need to log into your account to complete the setup process
- Your Master DVD should be formatted to work in any PC, according to ISO..standards Be sure that your DVD can be played in your PC or any DVD player. We make an exact duplicate of your DVD. Absolutely nothing is altered. It is therefore your responsibility to make sure it is exactly as you want it.
- All of these terms mean the same thing. It is just a difference in the terminology an individual prefers to use. They all are nothing more than a DVD-Recordable which contains the final version of the information to be replicated. This is what we start the replication process from.
- Glass Mastering is the first part of the process needed to actually make the “metal stamper” that is actually put into the injection molding machine to produce the CDs and DVD ‘s. The first part of the process is to convert the data into the actual highs and lows. These are actually done on a piece of glass. From that point the process continues and eventually the metal stamper is made.
- Authoring is the word used for taking the data and getting it into a format, which is readable when you put the DVD into the drive. In other words, there are programs and formats, which the person who creates the DVD uses to make the data actually usable. For example, if you want to be able to search for something on the DVD, someone, the “author” has to include the software to perform the search as well as the data itself. It is normally provided by the customer from his internal resources or he hires an individual to put it together for him. We require a finished product on a DVD-R ready for replication. One example is that we are often asked to take a video clip and put it on a DVD. The video must be put into an MPEG-2 format by an “Author”.
- Duplication (a.k.a. Burning) is a process where lasers “burn” pits into a dye that is manufactured inside the disc. Burning is the process used by the drives in virtually every home or work computer used today. Replication on the other hand, is an injection molded DVD Manufacturing process that makes use of a “glass master” and stamps the image (‘pits’, read as zeros and ones for data or ‘waves’ for video and audio) into the extruded poly.
- In simple terms, a DVD, commonly known as a Digital Video Disk, is very similar in size and appearance to CD’s. The principal difference is that due to improvements in technology, data can be recorded on both sides of the DVD and can also be recorded on two different layers on each side. (Don’t ask me how it’s done, I think it’s a miracle!) Nonetheless it can be done and this allows for massive amounts of data to be stored on a DVD. A regular CD can have roughly 650MB of data which is approximately what you can store on 500 Diskettes. DVD ‘s can store from 4.7GB to 17.0GB of information depending on how may sides and layers are utilized. Currently the primary usage of DVD ‘s is for video applications due to the massive amounts of space needed to do digital videos and a small but rapidly growing base of DVD players, principally in the home market.
- DVD-Video is the video (motion picture) element of the DVD format. This format can be played with a standalone DVD-Video player (What you will know as a DVD player) or a suitably equipped PC. I say ‘what you will know as DVD player’ because this is only one of the formats interpretations and player’s for other interpretations of the format will appear over time.
- DVD-ROM is the general computer version of the format, this works in much the same way as the current CD-ROM format, however it holds over 5x-10x as much data. DVD-ROM’s are used in the same way as current CD-ROM’s, all you need is a suitably equipped PC.
- DVD-Audio is the emerging format for storing audio only compositions on a DVD, it offers the option of multi channel audio (surround etc.) and video information for features such as song titles and alike. It claims to offer greater copy protection for the Audio CD Replication then today’s CD-Audio format and uses a different implementation of the encryption algorithm uses in DVD Video as the encryption being broken a little to easily for the standards body and the studios liking. DVD is the new generation of optical disc storage technology. DVD is essentially a bigger, faster CD that can hold cinema-like video, better-than-CD audio, still photos, and computer data. DVD aims to encompass home entertainment, computers, and business information with a single digital format. It has replaced laserdisc, is well on the way to replacing videotape and video game cartridges, and could eventually replace audio CD and CD-ROM. DVD has widespread support from all major electronics companies, all major computer hardware companies, and all major movie and music studios. With this unprecedented support, DVD became the most successful consumer electronics product of all time in less than three years of its introduction. In 2003, six years after introduction, there were over 250 million DVD playback devices worldwide, counting DVD players, DVD PCs, and DVD game consoles. This was more than half the numbers of VCRs, setting DVD up to become the new standard for video publishing.
- It’s important to understand the difference between the physical formats (such as DVD-ROM and DVD-R) and the application formats (such as DVD-Video and DVD-Audio). DVD-ROM is the base format that holds data. DVD-Video (often simply called DVD) defines how video programs such as movies are stored on disc and played in a DVD-Video (SACD). There are also special application formats for game consoles such as Sony PlayStation 2 and Microsoft Xbox.
- A single-layer disc can easily hold 150 minutes at the typical average video data rate if there’s only one audio track. Lowering the data rate slightly can accommodate over three hours on a single layer. Dual-layer discs can hold over four hours on one side.
- Playing an audio CD in a DVD player will not hurt the disc or the player. Some players use a single laser for reading DVDs and CDs, while others have separate lasers, but in either case there is nothing about the lasers that can damage a CD, nor is there anything about a CD that can affect the player.
- There are 5 types of format in all: DVD-5, DVD-10, DVD-9, DVD-14, DVD-18
DVD-5: Single Side / Single Layer, the volume is about 4.7 GB; Playing time: usually 100 minutes, up to 135 minutes; fair good quality, common resolution .
DVD-10 = DVD-5 + DVD-5, Double Sided / Single Layer, the volume is about 9.4 GB; Playing time: usually 200 minutes, up to 270 minutes; very good quality, good resolution .

DVD-14 = DVD-9 + DVD-5, Double Sided / Multiple Layers; the volume is about 13 G B; Playing time: usually 210 minutes, up to 370 minutes; better quality, high resolution .
DVD-18 = DVD-9 + DVD-9, Double Sided / Double Layers; the volume is about 17 GB; Playing time: usually 240 minutes, up to 480 minutes; The best quality, high resolution .
