Very much not true. The earlier movies shown this morning were in OAR (4x3). Reports are that all movies on TCM HD are OAR except in rare cases where they cannot get the right source. They have issued apologies in those rare cases. What he is referring to is that movies are uprezzed from SD to HD at TCM USA rather than using HD masters and downrezzing for the SD channel. However, it is all in the quality. If the PQ is excellent, it does not matter if was SD uprezzed or not. The opposite happens on AMC. They take good HD material and make it look awful.
