as akhl said, many facts of RAMAYAN are given in Shri mat bhagwat puran ,so the makers of RAVAN ON ZEE ,THE MAKERS OF SHOW JAI HANUMAN ,might be showing the facts from shri mad bhagwat puran also !!!
i saw in show jai hanuman !! tht when tulsidasji used to write RAMCHARIT MANAS every day HANUMANJI used to listen to what tilsidas ji used to write as tulsidasji used to write RAMCHARITMANAS while singing the dohas & then writing it !!! hanuman ji used to sit on the tree & sometime from behind the trunk of the tree ,under which tulsidas ji used to write RAMCHARIT MANAS without the knowledge of tulsidassji .
it was hanuman ji who asked tulsidasji to write THE STORY OF PRABHU SHRI RAM in awadhi lanuage so tht it cud be reached to the common ppl as VALMIKI RAMAYAN was in sanskrit !!!!
so i both THE RAMAYANS OF TULSIDASJI & VALMIKI JI ARE THE AUTHENTIC SOURCES !!! & SHRI MAD BHAGWAD PURAN !! ASLO !!!
yes both valmiki and tulsidas ramayana version r very authentics
and zee tv ravan is based on ravan wriiten book and ramayana south version
