Did the big drive swap today on my PCs; main machine now has a DVD (read only) drive and a dual-layer DVD writer, old PC now has a CD writer plus a single-layer DVD writer. Fairly painless, apart from having to reinstall Nero on the main machine to get dual layer support, and the discovery that the front-end program for Nero (startsmart) still hangs up on my PC; fortunately you don't need it if all you want to do is burn disks. Startsmart always says it has files missing - anyone come across this one? Now typing this on my laptop while watching the main machine burn a nearly full data double-layer data disk, just under 8gb, in 25 minutes - it can do faster if I pay big bucks for the x4 disks, but it hardly seems worth it. Annoyingly there isn't quite enough room for the whole of Veronica Mars S1 on a single disk - which is odd because the season fits fine on two single-layer disks, but never mind. Assume there is a rational explanation involving layers or something, but not sure what.
Anyway, all went well and a good deal less traumatic than I feared. Now have four gizmos that can write DVDs (the recorder, both desktop PCs and this laptop, though it only does DVD-R which is a pain) which seems like overkill, but never mind.
Later - appears that neither of the other PCs or the main PC's older DVD drive will read a dual layer data disk. I _hope_ that I won't run into this problem if I create a dual-layer playable DVD; if I do, I'm not quite sure what the point of having the drive is.
Tomorrow I'll take the old CD-R drive into work and shove it into the PC I use there - better than gathering dust here.
