Blu-ray/HD-DVD AACS specification. Unless you have a licensed AACS
decrypter (none exists in linux, note the specific use of the word
*licensed*) and ACCS-encrypted content (read: not cable) you will
never see any resizing of your video.

I like your confidence Robert.
Can you be sure there will be no AACS content distributed over cable? (Or DVB-x ?)
What would happen when the broadcaster's content source is Bluray or HD-DVD - with ICT embedded?
