Why can't I make a high-resolution surround DVD-Video disc? Why do I need DVD-Audio?
1.
Because DVD-Video MUST have some type of video, it does not leave enough room for uncompressed high resolution surround sound. The audio must be encoded into Dolby Digital or DTS. The DVD-Audio format was specifically created for high-resolution stereo and surround sound on DVD discs.

Is SACD the same as DVD-Audio?
2.
SACD is a high-resolution audio format created by Sony and is a direct competitor to DVD-A. SACD uses proprietary audio files called DSD (not PCM audio wav/aiff) using special hardware/software. SACD discs can only be mass-produced by manufacturing; they can't be "burned" from a DVD burner, nor can a single reference master be created in a studio. discWelder STEEL software can take the DSD audio files (normally used for SACD authoring), and convert them to burn a DVD-A title. This allows SACD equipped facilities to hand their clients a reference master disc while the SACD title is being manufactured.

What formats will STEEL support for converting from DSD to PCM?
3.
STEEL will convert DSD files into two PCM different resolutions. Standard conversion is set to 24bit 48kHz. If you require a higher PCM sample rate, a menu option can be set to allow 96kHz. The PCM files are stored to a folder of your choice if you wish to use them for further production or archival.

I hear that a DVD has "zones". How many "zones" are there and what are they?
4.
The DVD specification allows for as many as three zones on a DVD. They are: The Audio Zone (for high-resolution audio); the Video Zone (where your movies live); and The ROM Zone which is only accessible by computer. Each "zone" is separate format and requires a compatible player. .

What is a "universal disc"?
5.
A "Universal" DVD disc is one that will play both in a DVD-Video player and in a DVD-Audio player. It has both a DVD-Audio Zone and a DVD-Video Zone. Most Commercial DVD-Audio discs you purchase are actually "Universal" discs.
[ Top ]
What is a dual disc?
6.
A "dual disc" is a two-sided disc that is DVD on one side and a CD on the other. Many companies like 5.1 entertainment and Silverline produce dual discs putting high-resolution surround DVD-Audio on the DVD side..

Do your discWelder products play DVD-Audio discs on my computer?
7.
No, our discWelder products author DVD-Audio discs. However, there are DVD-Audio software players by WinDVD, PowerDVD, and by Creative Labs (included free with many of their surround cards).
[ Top ]
Can your discWelder products "rip" commercial DVD-Audio discs?
8.
We do not make any "ripping" software, just DVD-A authoring tools. As commercial DVD-Audio discs have copy protection, this is illegal in most cases. .

What DVD burners does discWelder support?
9.
Any DVD-R/RW or DVD+R/RW burner that supports the MMC (Multimedia Command) standard is supported in all current discWelder products. Dual Layer drives are supported. Dual Layer +R/RW burning is supported by discWelder STEEL.

Can I use MP3's with discWelder?
10.
The DVD-Audio format does not support lossy compressed audio formats such as MP3, WMA, etc. Although great for the Internet, these are far inferior sounding compared to the sound of DVD-Audio. You can import uncompressed .wav or. aiff files in our discWelder products.

Can I use Dolby Digital with DVD-Audio?
11.
DVD-Audio is a format designed to use all of the space on the DVD for audio. Then high-resolution audio can be put on the DVD. DVD-V uses almost all of the space on the DVD for Video leaving very little space for audio. DVD-Video needs Dolby Digital to shrink the file size down so the audio will fit. Since DVD-Audio is using all the space for audio, doesn't need to depend on lossy compression such as Dolby Digital. No lossy compression is accepted in DVD-Audio as it is a format meant for high-resolution stereo and surround audio

Will a DVD disc I created in discWelder BRONZE play in my DVD player?
12.
discWelder BRONZE creates DVD-Audio discs. The discs require a hardware/software DVD player that supports DVD-Audio. If you wish to create "Universal" discs that will play on DVD-V player as well, we suggest you upgrade to discWelder STEEL.

How do I know if my player plays DVD-Audio?
13.
Look at the official DVD logo. If it says DVD-A or DVD-Audio it can play the discs. If it just says DVD-Video it can play movies, but can't play the DVD-Audio zone on the disc.
[ Top ]
discWelder burns the disc fine but it doesn't play in my player. What’s wrong?
14.
Check to make sure the player is a DVD-Audio player. If the official DVD logo doesn't say DVD-Audio, it will not play the DVD-Audio format disc. Compatibility of the DVD R/RW media might also be a factor. There is still a fair amount of non-compatibility between types/brands of DVD media and players/burners. You may need to experiment with different type and brands until you find one that works best with your burner and players. Check with the burner and player manufacturers to see what types(and brands) of R/RW media is compatible with their models.

With my Mac version discWelder BRONZE, if I open BRONZE up with a disc already in the burner, BRONZE gives me an error.
15.
In Mac's "System Preferences" under Hardware, "CD's & DVD's" make sure other applications are not selected under the "When you insert DVD" questions. If so, that program will grab the burner, and not allow our program to access the burner. Otherwise wait until our program is opened until putting in a DVD into the drive

What is "mirroring" or "auto mirror"?
16. "Mirroring" or "auto mirror" is a feature of discWelder STEEL that automatically creates a video zone and menu structure on a DVD to create a "universal" disc that is playable on any DVD player. It includes a Dolby Digital encoder to encode all audio to Dolby Digital for playback on DVD-Video players.
[ Top ]
Can I create a surround disc in 24/96 using discWelder?
17.
Yes, if the sound files are lossless encoded with Meridian Lossless Packing (MLP). The 13.8mbs data rate of uncompressed 24/96 surround audio far exceeds the 9.6mbs maximum data rate throughput of DVD players. MLP is needed to bring the data rate below the limits of the DVD player without changing the audio quality (bit for bit).
[ Top ]
What happens if I try to create a surround disc in 24/96 without MLP?
18.
discWelder will automatically resample the file to 24/48 with its Resolution™ feature..
[ Top ]
What is the size limit of each of the DVD "zones"?
19.
The size of any or all of these zones is not pre-determined. You can make then as larger or small as you want. The only size limitation is the DVD disc itself.
[ Top ]
Can SurCode or discWelder products turn my standard stereo audio files into high-resolution surround?
20.
No, nothing can create true surround from stereo or mono files (say a helicopter flying in a circle around the speakers). Your surround receiver should already have settings to get the signal to all the speakers, or you can use your receivers Pro Logic II decoder to simulate surround sound. Up-sampling audio does not improve the audio quality of the sound file and takes up more space, so we see no need to offer up sampling as an integrated feature.
[ Top ]
What's lossless encoding?
21.
Lossless encoding is data compression for audio, but it doesn't "throw away" any audio. The decoded file is bit for bit the same as the original file. It maintains the original quality of the audio, but can't shrink the file size down as much as lossy encoded files. MLP is the lossless codec accepted in DVD-Audio.

Yes, discWelder STEELsupporst the creation of disc images.

Can I burn a standard red-book audio disc using discWelder?
23.
Using discWelder STEEL, you can choose to burn a standard red-book audio CD instead of a DVD-A title. .
