Have you seen Smita/Sumitra in X Zone!

I was so small a kid when I watched two episodes of this show called x zone! I didn't watch more coz I didn't had cable tv that time! I visited some relative and saw these episodes of and it was damn scary for me!

Now years after, out of the blue moon I started scraching my brain to recall what was taht made me scared at my mama's place, I cudn't recall the show name but cud recall A small girl named Neha and a ghost tree with green light...I googled out to find taht it was X zone and the particular episode was Neha' And when I searched it on Youtube I gotta know that Smita too is there as Not so kind elder sister of little Neha! Do you have any idea on which channel it was broadcasted?
Felt like sharig!
