I visited GluTV(http://www.glutv.com) website and found many different Zee TV Shows.I enjoyed watching Kasamh Se, Banoo Mein Teri Dulhann, Saat Phere, Sabaash India, Jai Ganesha,Naagin ,Alladin,Ghar ki laxmi betiyaan and much more.
Navigation was smooth enough and its video quality is excellent ...without any buffering time and we can easily forward or rewind videos without waiting for a second.
It took only 2 minutes to register on that site.I entered my email address and password and I was able to see Zee Network channels for free.
