ATAPI CD & DVD writer support is in the base OSR507 release.  The "Wd
Driver Supplement" you downloaded adds support for >137GB IDE hard
drives (only on systems with SCO Update Pack 1 installed).  It does add
ATAPI CD/DVD writer support to OSR506, perhaps you were mislead by that
in the docs.

You don't need a commercial product.  It's true that to date the
operating system doesn't include a program to write to CDs & DVDs; the
added support in OSR507 is at the driver level, making it possible for
such programs to work.

`cdrecord` is available in the SCO Skunkware collection
(www.sco.com/skunkware).  It can definitely write to CDs.  I've never
figured out whether you _must_ have the DVD-enhanced version to write
DVDs, or whether it only adds special DVD features like support for UDF
filesystem format.  Maybe someone who actually has a DVD writer can
comment...

Microlite's BackupEDGE and Lone Star's Lone-Tar support DVD writing.
Both are very well regarded by members of this newsgroup.  Both offer
time-limited demo versions on their web sites.  You might want to try
them and see whether they're worth the money to you.

Many of the products and books I review are things I purchased for my own use. Some were given to me specifically for the purpose of reviewing them. I resell or can earn commissions from the sale of some of these items. Links within these pages may be affiliate links that pay me for referring you to them. That's mostly insignificant amounts of money; whenever it is not I have made my relationship plain. I also may own stock in companies mentioned here. If you have any question, please do feel free to contact me.

Specific links that take you to pages that allow you to purchase the item I reviewed are very likely to pay me a commission. Many of the books I review were given to me by the publishers specifically for the purpose of writing a review. These gifts and referral fees do not affect my opinions; I often give bad reviews anyway.
