I have heard that as well (master last on chain). That is indeed the 
case here, POST shows LG GSA drive as secondary master & it is indeed 
the end of chain. I have been thinking a bit (always a dicey 
proposition) & I have a theory. I installed CentOS 4.4. CentOS is always 
based on an older (more stable, more thoroughly tested, more mature) 
code-base. This particular DVD burner is a relatively new (to the 
market, i.e. newly available) piece of hardware. I bet the installer had 
some newer driver in it that could cope w/ the *quite* newly available 
DVD burner, but the installed code has an older driver that can't handle 
it. Thoughts ?
