Netflix you enroll for HDDVD and/or BR. When you do you get an option to have preference for the HD DVD or BR disk over std DVD. I like this feature as I would prefer to get the the high def version if available. It also means I don't have to do a lot of searching to see if the HD version is available.
I am signed up for both. It seams to me they also ask what your preference is as a default if it is available in both formats but I am not sure of that.
They also have a list for both you can go to to see what is available in each format and what is soon to be available.
If you into HD, Netflix is the ticket.
