F11 Beta, no go on three different installs!

[psmith]

i have in the last few days been pulling my hair out trying to get an 
F11 beta install to work, first i started with the i686 xfce live spin 
for my acer aspire one, downloaded it from the fedora torrent link, used 
the win32 version of live-usb creator to copy it to usb and when i try 
to install it just seems to freeze after loading the kernel and initrd, 
when editing the boot line and removing the rhgb and quiet options i can 
see the initial hardware detection get to the point of the usb devices 
then it just freezes after giving the details of the last usb device, a 
synaptics touchpad

then i decided to write this iso to disc and try installing it on my 
desktop machine (GF8800, athX2,4GB ram, 500GB raid0) and it does exactly 
the same thing, freezes after detecting the usb devices, the last one is 
a logitech mx revo mouse

lastly i downloaded the x86-64 install dvd, burned it to disc and tried 
to install it to my desktop machine, this goes a little better as it 
actually makes it to anaconda, but when the propmt comes up telling me 
that it's beta software etc and i click install anyway it sends the kill 
sinal to everything and then tells me it's safe to reboot my machine! i 
noticed just after i hit the carriage return key to start the install 
from the grub page i can see lots of acpi errors flashing by but they 
are moving too fast to make out.

what has happened to the F11 beta install media?

has anyone any ideas what's up?
