The Anglicanization of the Roman Missal in 1970 (after the manner of the Book of Common Prayer), and the suppression of the Old Mass, much of whose text, including the Roman Canon, dates before the schism, is really at the heart it, along with a partial rejection of Vatican II. What marks Catholic traditionalists different from their Orthodox counterparts is that that Catholic theology requires them to be in communion with the Bishop of Rome (from which sprang the rupture with tradition). The non-application (in practice) of Summorum Pontificum within the borders of Buenos Aires was justly a cause of alarm for those who saw the Church heading in the right direction under Pope Benedict.
In the Latin West, there isn't much of a link between the law and prayer and the law of belief. Roman Catholic "orthodoxy" - as people perceive of it in the media or in the pew, is based on doctrine, not the law of prayer. A great number of Roman Catholic parishes have a Mass that has more in common with broad church (and low church) Anglicans than the pre-Conciliar norm. A "first among equals" ecclesiology, combined with Protestantized praxis, makes the Roman church more Anglican, not more Orthodox. But the Catholics still have the Pope and the Virgin Mary. I think the "pope emeritus" understood the link between prayer and belief, describing the devastation of the seminaries and the loss of faith from what he called the "false" Council of the media. The new pope, not so much. He may however prove to be a better instrument in cleaning out the rot within the Curia.
