BDP + Internet = New Trailers?

[Dirk Pepper]

I hope I'm posting this in the right place, apologises if not!

I have a Sony BDP-350 and when I move into my new house for Uni in a couple weeks I'll finally be able to but an ethernet cable in the back of the player and then into a wireless router.

Will this automatically upload any software updates? Also, a friend told me that if its connected to the internet, it'll retrieve the latest trailers associated with a film and play them instead of those pre loaded on the disc. Is this true?

Thanks in advance for your help!
