You will indeed need to register your new device for use with TV Anywhere. It's easy to do though so don't worry.
Using a PC/Laptop go to anywhere.virginmedia.com > My Profile > Device Settings. Remove the old device registration by clicking on the Delete button. Once you've done this, using the new device you are trying to re-register, open up TV Anywhere and log in. Try to stream Channel 4 and this should then prompt you to register the device.
If you follow the prompts on the screen, this will register the device for you and streaming will then commence
Let me know how things go.
