There's a fair bit of variation between brands and batches in media
size.  There is supposed to me a minimum (74 minutes), but it looks like
some CD-R media doesn't quite make it.

Given that CD-RW's are already more marginal then CD-R's I suspect the
80min hack is just too unreliable for most applications.  They do exist,
just google for "80min cdrw" and you'll get plenty of hits.
