Elementary streams contain either audio or video alone. This is the type
of stream that is most commonly used in DVDit!.
System streams contain multiplexed audio and video in a single file and
come in two formats:
Program streams. These are optimized for multimedia. DVDit!
supports program streams where there is only one elementary, DVD-compliant,
MPEG-2 video stream and one elementary MPEG-1 audio stream (44.1 or 48
kHz, 16-bit stereo).
Transport streams. These carry many program streams at the
same time and are mainly used for digital television transmission. DVDit!
does not support transport streams.
you use PCM audio in a project, the maximum video bit-rate is 8.3
Mbps. If you use Dolby Digital (DVDit! PE only), the maximum is 9.4
Mbps. The combined video and audio bit-rate must not exceed 9.8 Mbps.
The DVD specification also requires a sequence header before each GOP (the
sequence header contains information about the MPEG stream, such as aspect
ratio, GOP size and bit-rate). DVDit! does not support MPEG streams without
sequence headers. Check your encoder’s settings to ensure that it creates
sequence headers before you encode MPEG files for DVDit!
Most DVD Set top players will recognize CD-RW media BUT it will only
play the CD if it is a Red Book (audio) or VCD (Video CD).
If you insert a CD-ROM with a DVDVolume on it, the set top player will either
do nothing or eject the disc. Most PC DVD players can be coerced to play
the DVDVolume from any drive: hard drive, CD-ROM, DVD-ROM, DVD-RAM, DVD-RW,
Yes. Start by building a DVD Volume from the project onto your hard drive.
Take the “Video_TS” and “Audio_TS” folders out of the DVD Volume folder
and burn them onto the CD, along with your other ROM data, using any third-party
CD writing utility.
To add the cDVD player to your CD (DVDit! 1.1.3 and above), you must also
copy the folder called “intervideo” and the file called “Autorun.inf” (both
are in the “...\Sonic Solutions\DVDit! xx\Player” folder) to the root level
of your CD along with the “Audio_TS” and “Video_TS” folders.
With all versions of DVDit!, you can put DVD content on a CD-R. In version
1.1.3 and above, you can create a cDVD title, which actually puts a DVD
player on the disc itself so anyone with a CD-ROM drive can play back your
If you’re using an earlier version of DVDit!, you can still write DVD content
to a CD. However, these versions will not put a player on the disc for you.
In general, when writing to CD-R you should bear in mind that:
CD-R contains far less data than DVD-R (650 MB instead of 4.7 GB), so
your titles must be smaller. (A CD-R holds 15 20 minutes of high-quality
video — or more, if you do not need the same level of quality as a commercial
Some consumer (set-top) DVD players can recognize CD-R discs,
but will only play the CD if it is an Audio-CD (Red Book) or Video-CD
(White Book). However, all but the very earliest DVD-ROM and CD-ROM drives
in computers can read CD-R discs, so your title is playable on any computer
that has a software DVD player installed.
Only some set-top DVD players are able to read Video-CD discs. Check your
player’s manual for compatibility with Video-CD.
In DVDit!, writing to CD-R is the same as writing to DVD-R. You just author
your DVD project and tell DVDit! to write the project to your DVD-R or CD-R
recorder. DVDit! adjusts itself to write to the correct media automatically;
and if your project is too large to fit on the disc, DVDit! warns you, preventing
you from wasting discs.
