CSV file - show a given number of records at a time

i have a csv file with 72 records in it. i want to display just 8 at a time, and when the arrow keys are pressed, RIGHT and LEFT, i want it to show the next 8. HOW do i do that? do i have to redraw? I don't want to redraw cos i have a video in my sketch.

Here's my code (numerous attempts have been either commented out or deleted)

import processing.video.*;
import ddf.minim.*;
import ddf.minim.effects.*;

Movie mymovie;
Table myresource;
String Message;
PFont myfont;


void setup() {
  size(660, 600);
  background(69);
  myfont = loadFont("DejaVu.vlw");

  myresource = loadTable("neilyoung.csv", "header");
  println(myresource.getRowCount() + " total rows in table");
  showRows();
  loadMovie();

}


void draw() {
  if (mymovie.available() == true) {
    mymovie.read();
  }
  image(mymovie, 200, 20, width/3, height/4);
  KeyPressed();
}

void KeyPressed(){
   float current = mymovie.time();
   float entire = mymovie.duration();
   if (keyPressed) {
      if (key == 'f' || key == 'F') {
         mymovie.jump(current + 12);
       }
       else if (key == 'b' || key == 'B') {
         mymovie.jump(current - 12);
       }
       else if (key == 'e' || key == 'E') {
         mymovie.jump(entire);
       }
    }

}

void showRows(){
  int numRows = myresource.getRowCount();
  int count = numRows/8;
  int lines = 0;
  //String[] albums = loadStrings("neilyoung.csv");
  textFont(myfont, 22);
  text("Neil Young Albums", 30, 200);
 // for (int i= 0; i < numRows; i++){
//do{
    for (int j=0; j<numRows; j++){
      TableRow row = myresource.getRow(j);
      int a= row.getInt("year");
      String b = row.getString("artist");
      String c = row.getString("title");
      textFont(myfont, 16);
      Message = str(a) + "  " + b + "  " + c + "  ";
      text(Message, 30, 230+ j*27);
     // if (j == count){
       // lines=j+8;
       // myresource.removeRow(0);
       // break;
     // }
    //}///}while(lines< numRows);

 //}
}

void loadMovie(){
  // Load and play the video
  mymovie = new Movie(this, "harvestmoon.mp4");
  mymovie.play();
}
