[texdvd] single-layer vs. otherwise

[Stephen Kellat]

I’ll have to look into sourcing dual-layer discs.  MicroCenter doesn’t have much choice available on its site for purchasing: https://www.microcenter.com/search/search_results.aspx?Ntk=all&sortby=match&N=4294961470+4294810112+4294821956

The selection at B&H Photo Video isn’t much broader: https://www.bhphotovideo.com/c/search?q=dual%20layer&sort=BEST_SELLERS&filters=fct_category%3Ablank-cd-dvd-blu-ray-discs_13279%2Cfct_media-type_684%3Advdplusr

This is looking increasingly difficult.  I know in the Ubuntu context we gave up on sticking to the CD-ROM disc image size several years ago and we’re on track to go past DVD single-layer size for a live installer disc yet.  All the downloadable disc images there are already ISO/Hybrid images so they can be both burned to disc and written to pen drive now.

Hello 2024 TeX dvd folks - the TeX Live pretest is coming along, and
the form for people to request dvd's should be ready pretty soon.

Unfortunately, the TL image on its own, even when I take out all
platforms except the big three (GNU/Linux, Windows, macOS), is still
well over 4.7G and hence will not fit on the basic single-layer DVD. Nor
will MacTeX, in its .pkg form.

Even if I started removing large packages to get below 4.7G (not a fun
prospect), it's unlikely I could do that for more than one or two
releases before it would just become untenable.

Bottom line: I hope you-all will be able to write in one of the
"double-size" DVD formats, whether dual layer or whatever. Because I
don't see a viable alternative.

I'm less worried about reading, since I think nearly all DVD readers
sold for the last decade or two can handle those formats. If not, well,
a new DVD reader doesn't cost much.

Thoughts? --thanks, karl.
