FC3 Install from DVD - possible?

[Bob Hartung]

Hi all,
   I have burned the DVD iso image to a DVD.  Upon starting up to 
install the DVD is found then:

1.  typing "linux mediacheck" is totally ignored and anaconda starts

2.  All goes normally until it comes to locating the installation 
media.  DVD is not on the list and Anaconda steadfastly refuses to 
find the DVD.  It does as for the CD however.

My questions:
1.  Is it really possible to install from a DVD iso image?  Is 
there a switch that needs to be entered at the boot prompt?

2.  Why does it blow by the "linux mediacheck" entry at the 
"boot:" prompt?

All help appreciated!

Bob
