Yup, you're talking about the two 8-man dungeon runs at the end of ARR. I just ran these for the first time last night. I went in knowing that these two instances are probably the fastest tomes you'll ever get, and I let everyone know that I was ok with skipping cut scenes as I didn't want to slow anything down, and I was also just wanting to get it over with.

What I did was actually view the cut scenes on youtube before going in as I would rather have dealt with the spoilers than have them be deflated by looking at them after the battles took place. Then I saved the videos of the boss fights. Now I just got to download the content, do a little editing and I should have a full vid

I still wish I would have been able to experience the instance and cut scenes all at once though.
