This looks to me as if you're having problems with your blanks. I've seen something like this a couple of times, but in each case it basically didn't get beyond the initial write of (in your case, anyway 1867776 bytes). I'd *strongly* recommend getting at least some +/-RWs to play around with. At least like that you don't end up with a pile of coasters, and it might help identify the issues. All my burn failures (about 40% of total!) have been with DVD+Rs, though admittedly a cheap no-name brand bought in Taipei. I've found that they work OK if I burn them at speed=1; if I use the default speed of 4, they usually fail. > Aside .. seems like a lot of tools depend on cdrecord to work, and > it seems cdrecord with its key situation is volitile and requires > userland knowledge to sort out.. so a bad situation :( I've given up on cdrecord.
