stange boot vista dvd issue

Hi everyone,
i've burned the .iso file in the correct way, but still can't boot from that DVD on my IBM Thinkpad R40. I know i burned it right because i can correctly boot with the same Vista Beta 2 DVD on other machine and from Virtual Machines.
The thing is that i can correctly boot my PC from any other bootable CD/DVD but not from Vista Beta 2. The boot sequence is correct (otherwise i wouldn't boot from Windows XP CDROM), i also checked if i have latest BIOS and DVD drive firmware and they are already up to date.
Waird, considering i could boot with previous Vista DVD with no preblems.
Anyone has an idea what to do next?

I know. My question has been posted multiple time by mistake, i kept getting an error message and tried several times but the question got actually posted every single time.
Sorry about that, please ignore the extra ones.
