There is a scene with Bobby, Pam and Jamie in Season 9 that was deleted. Not sure if it´s in RTC too. Then there is the "I´ll Come Back" clip of Sue Ellen´s last scene included in the recap of Season 11, which we never saw or heard on "Reel Life".
And another scene with Ray and Wes in Season 9, only seen in the episode preview. And, allegedly, another scene with Pam and Mark, the latter fainting / dying in her shower, in the Dream Season (though this one sounds like an urban legend). And, of course, the clips of every suspect shooting J.R. and Bobby (not Kristin or Katherine).
Voilà Holly hiding at Ewing Oil,
waiting for give J.R. what he deserved...
(Fake pic, in case you doubt it!)
I seem to remember a couple of brief scenes with Angelica in the episode previous to "Masquerade" edited out from dvds.
In Spain we didn´t see the cliffhanger recap of "Conundrum", replaced by a recap of the previous episodes. So far this is all.
Edit to add another scene with the family (including Lucy and Jamie) having breakfast by the pool, that never was aired (see pìc below). Those two only shared one scene in Jamie´s first episode aside from the deleted one.
I also found this video with three other deleted scenes from season 9 opener:
And that gore-ish scene with Ray and Jenna driving Lucas home and giving a damn of Bobby´s wrecked car!
