The Samsung BD-D5500 does have a deep color setting - will check that tonight. In theory the 1712 supports it over high speed cables and doesn't look like it can be switched off there... With only the BD player connected to the AVR, was able to recreate the problem. Ditto with just the the SA 4250HD cable box (adjusts resolution to broadcast, not locked on 1080). Don't think the SA 4250HD has a setting for deep color. Can't really bypass the AVR - TV has only one HDMI in and the sound on it sucks... Could try composite cable to the AVR though for the SA box.
