Hey guys. The x86 LiveCD is currently sitting at ~838MB, as evidenced by the above mirror link.
AMD64's LiveCD is only 670MB, so it's not affected by whatever hit x86. Regardless, the x86 media can't be burned to a CD.

Fyi, this is apparently fixed with livecd-i686-installer-2008.0_beta2-r1.iso
I'm not sure what was wrong though.

This should be fixed in 2008.0, which is now released.
