HP Pavilion Notebook zv6130us: DVD Burner Not Mountable

Hi. As I have problems with installing 64 Studio in my desktop computer (see other thread started by me), I once tried to install 64 Studio in my laptop. It's an HP Pavilion Notebook zv6130us purchased October of 2005. Specs: AMD Athlon64 3200+ Single Core Processor, 512MB RAM, 80GB HD, DVD Burner, 4 USB Ports, 15.4" widescreen, built-in sound card, and that's about it. When booting up the installer, I saw a blank screen. To remedy this, I had to take my laptop to the monitor, plug in the VGA from the monitor, do Fn+F4 twice, which will cycle between external monitor only and laptop monitor only, and then disconnect the external monitor from my laptop. This is not only 64 Studio, but also happens with Ubuntu Studio, since they only provide alternate installer. But with Ubuntu Studio, my DVD burner is mountable, so I was able to complete the setup without any problems and that I'm ready to use Ubuntu Studio. However, I wanted to get away from Ubuntu Studio, because I really thought about trying a better audio studio-optimized distro. So, after I work around the blank screen problem, I followed the instructions and when it comes to mounting my DVD burner, it can't mount my DVD burner, so I had to quit my installer. Any ideas? It's 64 Studio 2.1 that I'm trying to install.
