since the last ECM there is no 100% receiver that can AU DreamTV and i think there is no new S/W patch for any receiver since then.
why not try a viable alternative, get skystar2 pci card for your computer. if you manage to set up your SS2 properly with the right combination of plugins you will have a better chance of DreamTV 60-80% AU. this is were i get my keys and shared it here in the key section. you on the other hand will benefit on this SS2, you don't need internet to get DreamTV keys. just watch DreamTV on your pc there you can get the keys for your Angelbox...
but then again, you can buy yourself a DM500S if you really want it.
PS... if i don't post DreamTV keys it means i am DRUNK or playing PS3
