<p class=MsoNormal>I believe the media check simply checks the physical disk
(ie making sure it can read from all sectors, etc). If this is the case
then it is entirely possible that the date required for the install is not on a
part of the disc the media check detects as faulty.<o:p></o:p></p>

<p class=MsoNormal>On a separate, but related note, for downloaded files that
you burn to ISO, always make sure to verify the md5 sum. A corrupted
download of an iso file will burn just fine, but still result in a failed
install.<o:p></o:p></p>
