New ICT flags in Blu-ray discs will detect analog connections and downconvert to 540p forcing you to use copy-protected HDMI to get full HD.
If you use the “three colours” inputs for your blueray player you may be in for a bit of a surprise on some new blu-ray discs. Alarmist Hollywood douchebags think that “plugging the analog hole” will prevent piracy. Maybe no one told them that AACS (the encryption scheme used in blu-ray discs) has already been thoroughly cracked and broken. All this is going to do is annoy the hell out of legitimate paying consumers who just won’t understand why they have to get an HDMI cable.
