Wtv-020 sd-16p cannot work with ethernet

Hi....i'm new in arduino.....my question is..

I'm using arduino uno REV 3 and Wtv020sd16p module mp3 player....this modul has work well....but if i'm join in Ethernet.begin in Setup mode(), the modul cannot work.....Please help me....this my code..

#include <Wtv020sd16p.h>
#include <SPI.h>
#include <Ethernet.h>
int resetPin = 12;
int clockPin = 8;
int dataPin = 9;
int busyPin = 13;

const int buttonPin1 = 4;

int buttonState1 = 0;

byte mac[] = {0xDE, 0xAD, 0xBE, 0xEF, 0xFE, 0xED};
byte ip[] = { 192, 168, 0, 3 };

Wtv020sd16p wtv020sd16p(resetPin,clockPin,dataPin,busyPin);

void setup() {
pinMode(buttonPin1, INPUT);
wtv020sd16p.reset();
Ethernet.begin(mac, ip); ->> if i put this code my module cannot work

}

void loop(){
buttonState1 = digitalRead(buttonPin1);
if (buttonState1 == HIGH) {
wtv020sd16p.playVoice(2);

}
}

The ethernet shield uses SPI for communication between the ethernet shield and the Arduino. On a 328-based Arduino, that involves pins 10, 11, 12, and 13. You can't use those pins for other purposes.
