As I wrote previously, DVD is more like Internet delivery.
You cannot directly read data from DVD - I'm talking about ServerPac,
because for z/VM installation process DVD is perfectly ok.
In fact I have never orderded anything *from IBM* on DVD, but I assume
the first step is upload DVD content to HFS. That means you require a
lot of HFS space, then a lot of space for unzip and RECEIVE processes.
Compare it to tape: you receive small PDS from tape then submit single
job, which reads all the data from the tape. For CBPDO you get relfiles,
for ServerPac you get DLIBs and TGTs. Much less space, much less
potential problems to diagnose.
Last, but not least: when you order physical media, you get a box(es)
with few manuals and a lot of CDs and DVDs. If you want to download it
you have to assign many gigabytes of PC storage of ISO images, and (more
important) you consume a lot of Internet connection bandwidth.
(of course this is for Internet delivery, not for DVD as replacement for
tape media).

Assuming the installation procedures are as desired/requested, is there any
problem with DVD media when/as physical media distribution is required?
They're pretty large for software distribution purposes -- over 4 GB each
at least before compression. Certainly large enough to get started up and
then (if desired) get attached to storage and/or network -- including your
software product repository.
DVD is the only common, universal media type for mainframes, isn't it? With
a DVD path I know I'll always have an execution path, even if I'm at an
unexpected and "alien" DR site. With tape I've then got to worry about
whether it's Type X Vendor Y tape, and that's assuming there's even a tape
drive at all (not a given).
I'm certainly not opposed to anyone who wants to use a particular type of
tape for their own media distribution needs. But isn't DVD what IBM and
other mainframe software vendors ought to be using on those occasions when
they're shipping something physical. Also bearing in mind that'd it'd at
least be helpful if all the vendors could agree on one media, and they're
unlikely to agree on anything except the universal format. There's also the
fact that practically anybody can record DVDs, and they're trivially easy
to ship, so any delays associated with media
manufacturing/recording/distribution are at least minimized relative to
other formats.
