Comment 4 Wang Zhenyu 2008-06-02 02:11:22 UTC 
yeah, current main profile@main level only, so no 4:2:2. 4:4:4 is not required for mpeg2.
Comment 5 Wang Zhenyu 2008-06-27 20:33:36 UTC 
I don't think we need to care this for i915 or even on newer chip. 4:2:0 is massively used and the standard for future digital tv. So mark this as wontfix.
