Hello? I could really need some advice =(

I tried nearly everything possible. I have used 3 different DVD brands (Sony, Philips, Verbatim), tried DVD+R, DVD-R, DVD-RW and whatever. I started the installation with -f, with -x -f, with cpus=1 -f -x ... nothing worked for me. It always stops either at "Waiting for boot device", at the wallpaper right before the installation should start or somewhere between.

Greetings,
Tom

I fear that the same things will happen with the 10.5.2 release o.O
