The 16 pin device turned out to be a multi-bit A/D converter, not an I2C controller. After reading the above again I believe I understand what 20 pin device you are talking about. Just right of the composite video input past the Xtl in this photo: http://c1.neweggimages.com/NeweggImage/productimage/15-260-007-15.jpg ...I'll have to take another look. The remote for my kworld 120 has 35 keys. (My kworld 110 remote has about 45 keys.) ...thanks for your help. -- video4linux-list mailing list Unsubscribe mailto:video4linux-list-request@redhat.com?subject=unsubscribe https://www.redhat.com/mailman/listinfo/video4linux-list
