Haven't seen the video, I'm at work, but from all of the information, I'd say so.

I've seen P0422 on a couple Volvos and on one A4. All of them needed to replace the catalyst.

I would think its your cat... rattle should be evident at idle... take the longest screwdriver you can find... put one end on your cat and the other to your ear and have a listen. Have you noticed any decrease in performance? When my cat went, I could only boost 1-3 psi, and was painfully slow.

yeah i there is a big decrease in performance. but if i clear the cel, the car runs better until it comes back.. its soo anoying driving around with all that rattling!! y drive a nice car that sounds like shit! embarressing.. think i'm gonna try and pull the cat out today and run the engine and see if the sound goes away. whats the best way to get at the lower nut at the rear of the cat.. i also threw another cel today.

I personally wouldnt run a car without the cat on... their will be nothing hitting the o2 sensor and If I remember correctly that is bad....
