Raphaël,

Let me explain our one can conclude on the 3 questions:

You take the som  of the ranking of  3 questions:
the lowest som wins:

Media RSS 2+1+3= 6
EXIF	1+5+1=  7
Youtube 4+2+4=  10
TV-Anytime 5+7+3=15
ID3 frames 5+4+7=16
MPEG-7 =8+6+2=  16
EBUCore 7+3+8=  19

I hope this clarifies the calculation.

Thierry.
