Problem in getting live quotes from yahoo finance

Dear Members,

I am having a Java Scipt based utility for getting live quotes of Indian stocks from yahoo finance. But from 28th January 2013 the quotes for many symbols are not updating.
=================================
See quotes for jindal steel & power not updating
====================================
SYMBOL -----Last Traded P.CLOSE OPEN HIGH LOW
JINDALSTE.NS Jan 28 - 430.55 433.45 432.35 436.70 427.00

========================================
The quotes for following symbols started updating after adding" -EQ "
============================================
KFA- EQ.NS 5:04am - 11.10 10.60 11.00 11.10 10.75
MTNL-EQ.NS 5:04am - 23.30 23.55 23.50 23.60 23.25
NHPC-EQ.NS 5:05am - 28.80 28.70 28.70 29.15 28.25
SAIL-EQ.NS 5:04am - 81.10 80.75 80.60 81.60 79.70
TCS-EQ.NS 5:04am - 1410.00 1414.70 1409.05 1415.00 1401.85

========================================
Adding -EQ not worked in following scipts as limit of 9 characters in quote is surpassing so I have to suffix .BO instead of .NS and quotes delayed by 10 minutes.
========================================
