This should be fine, but it does come down to the system you have. Current-generation notebooks are fine, because the GPUs inside the notebook should handle the encoding required for Blu-ray. If not, you can get very slim, USB-powered Blu-ray drives.
Current-generation notebooks should be fine, and I would be very surprised if any recent notebook couldn't handle an internal drive. If you'd like to shoot me an e-mail with your notebook model, I can look into it more for you.
