I tried both, and see: cdrecord complains about not being able to set
certain priorities while being run as user, which induces a high risk
for buffer underruns. So I have my answer for that.
Another cdrecord-related question. Usually I should be able to copy a CD
as simply as that:
$ dd if=/dev/cdrom of=copy.iso
Then insert a blank CD, and:
$ cdrecord -v -eject dev=/dev/cdrom copy.iso
Now I did that for data CDs, and it works very well. I thought, normally
this *should* also work for audio CDs, so I gave that a spin. But
everytime I try it, dd stops short and gives me an "Input/output error"
I tried three different audio CDs, all three in good state. I can listen
to them OK on the PC. But all I get with dd is a zero-byte-length
Any idea what's happening?
