They were showing the movie Krish instead of Ramayan. I think they did it to adjust the extra time when RKR was over. Today we will surely get to see Ramayan
Sometimes they don't show an epi if they want to show a movie instead...but I don't think they stopped telecasting it or we'd have known.
Anyhow...my advice is that if you really want to see Ramayan in full, go to the HQ vids uploaded by NDTV Imagine on youtube. This new version is highly edited.
