Robinson Crusoe question

TCM showed the Luis Buñuel version of The Adventures of Robinson Crusoe again this morning. What I noticed as I was flipping through the channels, however, is that this time it was letterboxed, and the print looked somewhat crisper than I remember it being when TCM showed the movie during 31 Days of Oscar back in February. Am I correct in this?

I suppose I could be misremembering what TCM did back in February, but I distinctly recall a blurry print that looked worse than your typical panning and scanning. I didn't record the February showing, and if I had, I would have watched it since then and erased it. The movie doesn't seem to be available on DVD either, so I have no idea what prints of this movie are available.
