OK, here's my status. Why I didn't think of it before I don't know, but it occurred to me that my ECDC 5 Plat disk is considerably older than the applications disk that came with this box. Since DCD was initially working, before I applied the ECDC XP update, I did a custom install of DCD from that apps disk.
Now I'm able to again read the CD/DVD-R's (at least the several I've tested so far) that had been unreadable!
I haven't had time to play around with it too much, but I note some annomalies.
SOME CD/DVD's don't open in Explorer for about 45 seconds after insertion.
With the DVD-R, Explorer doesn't read the vol label - before the disk is inserted the drive is listed "DVD-RAM Drive (D:\) - after the disk is finally opened, the drive label is "CD-Drive (D:\).
I wonder why. Has anyone encountered a patch for this?
With the CD-RW, the vol label is correctly read in Explorer for the first CD inserted; with subsequent CD's Explorer continues to show the label for the first CD. However, rt-clk | properties does correctly show the current CD's vol label.
With both CD and DVD drives, autoplay starts, though I've selected "take no action" for the autoplay properties of both.
With some disks, when I click on a folder, it takes 30 - 45 seconds for the folder to open. On one DVD-R, when I clicked back in the tree, the cursor (but not the system) froze, and I could not eject the disk (rt click - eject).
I haven't applied the ECDC XP update, as I don't want ANY unnecessary Roxio files installed. Do you think that update could correct some of these issues.
Thanks a bunch for interest.
