Oh, I see. thanks for pointing that out.
Now that you mentioned it, I recall also asking the same thing to a salesman at Ansons more than a year ago. The player wasn't blu-ray or HD DVD but was in a sealed casing proprietary to the brand and not for sale. It would play a 20-30 minute HD material on a loop so it gets displayed over and over. So it must be using a hard disk alright.
