Cannot install OSX Leopard on apple emac computer?

I'm writing this on Linux where we burn cds and dvds all the time and I do have a suggestion: I recently had to go back to Windows for a week last may when my laptop was stolen and I had to wait for the ISP guys to install -- they got all hot and bothered by my brother's Mac and the impression I get is they were not about to TOUCH Linux. I found the usual Windows CD burning software problematic at best however usually there were ways to burn things I could read on reasonable OSes. Anyhow rule number one for burning a boot disk is burn it slowly. ALWAYS. 2x is best 8x max and 4x is acceptable. That minimizes the chance of data errors. Also Windows burning programs want to burn things as windows disks -- I've had ISO files which had extra data added besides the iso file -- making them pretty close to useless of course. So make SURE you are burning ONLY the iso file. If you can open your disk on tiger that is what you should do before you try to burn it. It could be one or the other of the things I mentioned. InfraRecorder, the Open Source burner which uses UNIX technology and which Ubuntu recommends is good at writing ISO files and at giving you control over the process, but the truth is I've never used it for burning it dual layer. DO NOT use Windows native software. Their proprietary/lock-in mania makes it UNRELIABLE for any reasonable OS.
