FAQ

DVD (Digital Video Disc or Digital Versatile Disc)
DVD is an optical disc storage media format that can be used for data storage, including movies with high video and sound quality. DVDs resemble compact discs as their physical dimensions are the same but they are encoded in a different format and at a much higher density.

1. What is the difference between Duplication & Replication?
Duplicated discs are writable discs that can be copied in small quantities.The process of duplicating is the same as it is on a desktop computer. The information or video is burned on to a blank disc. Duplicated discs can be made in any amount in as fast as one day. Duplicated DVD-R discs will play back in most new DVD decks and computers, but they are not as reliable or compatible as replicated discs.

Replicated discs are injection molded from scratch in multi-million dollar replicators. Replication discs are more reliable and considered "retail ready" discs. The main drawback to replication is that it requires a minimum order of 1,000 discs and takes about 10 business days.Replicated discs play in all players and are highly recommended for large quantity orders.

Duplication utilizes blank DVD discs where the information or video is "Burned" onto the disc. Replicated discs are manufactured from scratch from plastic pellets. Duplicated discs are more delicate than Replicated discs.

2. What are the advantages of duplicating DVD-Rs?
DVD-R discs can be duplicated quickly and in smaller quantities. You can order anywhere from 1 to 2,000 DVD-R discs. Many DVD-R discs have printable disc faces for your custom artwork. Replicated DVDs require long set-up times and complicated art requirements that require a lot of pre-planning and take a longer time to complete.

3. What are the advantages of Replicating DVDs?
Replicated DVDs take longer to make, but are considered "Retail Ready" discs. Replicated projects are usually ordered in large quantities for retail or corporate distribution. Replicated discs will playback on all dvd players. Replicated discs are usually made with high quality silkscreen or offset printing on the disc without using stick-on labels. Replicated discs are better overall, but they have a minimum order of 1,000 and take 10 days to make.

4 . Are there any playback limitations with DVD-R? (Will it play in my home dvd player?)
Quality burned DVD-R discs will play in most dvd drives and decks. Some older DVD decks may have compatibility issues. Please contact us if you have a specific question about your DVD player and it's compatibility with DVD-R discs, or search for your player's compatibilityHERE.

5. Why do I want to put my video on DVD?
The picture quality is considerably better on a DVD than on a VHS tape. Also, unlike tape, DVD is a medium that will archive your video for up to 250 years without any degradation. Even if a new technology comes along, you will be safe with your untainted DVD master. Mpeg2 is the file format used to encode DVD video. This format is easily transferable from hard drive to hard drive. VHS and 3/4 tape machines are growing more and more uncommon while DVD players can be found for $60 and less. All of the major retail chains such as Blockbuster and Best Buy will eventually abandon VHS as a viable format for video. VHS decks will eventually not be sold and will go they way of the 8 track tape and audio cassette. Do you have any 8 track tapes?

6. How do I get my video on to DVD?
To get a video on to a DVD disc, the video and audio must be encoded into data. The video is encoded as a file format called MPEG2. The audio is simultaneously encoded as Dolby Digital. This information is then burned directly to a DVD-R disc and that's it!


CD (Compact Disc)
A Compact Disc (or CD) is an optical disc used to store digital data, originally developed for storing digital audio. The CD, introduced in 1982, is the standard playback format for commercial audio recordings as of mid-2006. An audio compact disc consists of one or more stereo tracks stored using 16-bit PCM coding at a sampling rate of 44.1 kHz. Standard compact discs have a diameter of 120 mm or 80 mm. The 120 mm discs can hold approximately 80 minutes of audio. The 80 mm discs, sometimes used for CD singles, hold approximately 20 minutes of audio. Compact disc technology was later adapted for use as a data storage device, known as a CD-ROM, and to include record once and re-writable media (CD-R and CD-RW). CD-ROMs and CD-Rs remain widely used technologies in the personal-computer industry.

1. What is the difference between CD-R and CD?
A CD-R is a blank disc that has information burned on to the surface. A CD is molded from scratch with the information on the disc. CD-R’s a re duplicated in smaller runs, while CDs are replicated, usually several thousand at a time. Most CD-R’s can be read by any computer drive. Some may have compatibility issues.

2. What is the Difference between Audio CD-R and Data CD-R ?
An audio CD-R is formatted to play back audio recordings in Music CD players and computer drives. They are similar to the CDs you buy at a music store. Data CD-R’s contain data files and do not play in conventional music CD players. It is possible to burn audio files on to a data cd, but they will read back as data files and not as music.

3. What is the advantage of making CD-R’s?
CD-R’s are very compatible with most players and are very useful for copying short run projects up to 2,000 discs. CD-R’s can be duplicated in a few minutes while Replicated CD’s require long setup times and must be ordered in large quantities.

4. Are there any playback limitations with CD-R (will it play back on my home system?)
We use top quality blank CD-Rs. Even so, it is possible that a CD-R format disc will not play back or open properly on older CD players and computer drives. Please contact us if you are having any kind of compatibility issues and we will do our best to try and fix the problem.

5. How do I get my music on to a cd?
You can bring in your master tape to us and we can transfer it to CD. You can also burn music on to a cd yourself. Most CD burning software can handle this process with ease. Please make sure that the music you are burning is at CD is standard 16 bit/44.1kh before tying to burn it as music. Also remember to choose the “Audio CD” option in your burning software so that you do not end up burning your music as a data disc (which will not play back as music!)

6. How do I get rid of the spaces between tracks on my cd?
Most Cd burning programs automatically insert a two second pause in between music tracks. If you are making a mix cd and do not want to hear pauses in your music, please email us with the name of your burning software and we will walk you through the process.
