The whole subject of PXE booting Ubuntu (and presumably also Mythbuntu) 
is shrouded in mystery and confusion.  I've not tried with Myth, but I 
did wrestle my way to getting Ubuntu to boot that way.  There is still 
much mystery and I am still confused, but I have one way of making it 
work.  I'll describe it in case it  helps you.

The tftp boot configuration file (in my case ./pxelinux.cfg/default from 
the tftp root) is this:

   DEFAULT menu.c32
   PROMPT 0
   NOESCAPE 0
   ALLOWOPTIONS 0
   TIMEOUT 600
   MENU TITLE Boot images
   LABEL Ubuntu Install
   kernel ubuntu-12.04.4-desktop-i386/vmlinuz
   append boot=casper netboot=nfs nfsroot=10.18.78.254:/home/iso/ubuntu- 
12.04.4-desktop-i386 initrd=ubuntu-12.04.4-desktop-i386/initrd.lz -- 
splash only-ubiquity

The tftp root has subdirectory 'ubuntu-12.04.4-desktop-i386' in which is 
initrd.lz and vmlinuz, copied from the 12.04.4 directory tree.  The IP 
address of the server on which this is all running in 10.18.78.254, and 
it exports the whole 12.04.4 tree by NFS; it's then picked up by the 
"netboot=nfs" and the "nfsroot" spec.

"--splash" and "only-ubiquity" are magic spells I saw in one of the many 
articles I read about this; my setup works with them and I'm not about 
to take them out just to see what happens.

I hope that helps.  I share your pain ...
