Here’s link to one of the vids on YouTube. The reporter is speaking in Spanish, but it’s a side view of the bow. The Saudi sees him, smiles, and holds out his left hand. Obama quickly goes over, and bows — there is some debate on whether there was a kiss of the Saudi’s ring, but the clear view is obstructed. As others have pointed out, it does appear at one point that the King’s hand has been turned palm-down, at the same time Obama’s mouth is right about at that height during the bow...
As for the kiss - definitely up to speculation. As for the bow — no misinterpretation can possibly be made after viewing the video.
I was going back over my pings, and ran across my post to you. I realized I forgot to put in the link! I hope you found it on the thread, but if not, here is the link;

[The bow happens about 45-50 seconds into the video]
Sorry about that...
