"PLEASE NOTE: EDIT CONTAINS CONVERTED 4:3 MATERIAL               Brazil's biggest city - packed with protesters for yet another night.               This time an estimated 50, 000 turned out in Sao Paolo to voice their discontent.               A television news vehicle and a police booth were set alight.               There were some scuffles between protesters and police in what was otherwise a largely peaceful demonstration.               Protests began with an outcry over a rise in bus fares.               They've grown steadily into a wider backlash against other issues including poor public services, police violence and government corruption.               The protesters say it's time for change.               (SOUNDBITE)(Portuguese) PUBLIC WORKER LEONARDO MAURO SAYING:               \"We're here to improve this country at a crucial time, and with the principle of freedom we can achieve everything in this life.\"               Brazilian President Dilma Rousseff on Tuesday sought to defuse the wave of protests.               She acknowledged the need for better public services and more responsive governance.               Brazilians haven't taken to the streets in such numbers since the early nineties.               Then economic volatility and a corruption scandal led to a presidential downfall."^^<http://www.w3.org/2001/XMLSchema#string>
