My understanding is that with the ICT (image constraint token) off,
you will get 720p/1080i.  With the ICT on, you will get 520p.  Setting
the ICT for the media is up to the producer of the disc.  Discs with
ICT set are supposed to be labeled as such.

If you use HDMI for video and a digital link for audio (which is what
I'm doing) you get standard 5.1 digital audio (not the super-fancy
uncompressed 7.1 audio, though).  I've got a post-HDMI Harmon/Kardon
receiver, but something went wonky with the HDMI switcher, so I don't
have video going through it anymore.

In fact, from my research the ICT isn't supposed to cause audio
downgrade.  There's also a Digital Only token, which completely shuts
off analog output, but I don't think anyone's planning on using that.
