OES BETA3 ISO

I cant get the iso's to read under loopback or burning to cd.

I get the following error under linux from a burnt cd.

Interleaved files not (yet) supported.
File unit size != 0 for ISO file (1792) .
ISOFS: changing to secondary root.

Windows will not open or mount an iso either.

Windows says the directory is corrupt.

I have run md5sum on both iso's and they are good.

Any idea's?
