How to apply imagecache to video thumbnail in view - quick fix

I did following steps to apply imagecache preset to the video thumbnail image.
1. Created tpl.php file for view
2. Did following changes into the tpl.php file

<?php foreach ($fields as $id => $field): ?>
  <?php if (!empty($field->separator)): ?>
    <?php print $field->separator; ?>
  <?php endif; ?>

  <<?php print $field->inline_html;?> class="views-field-<?php print $field->class; ?>">
    <?php if ($field->label): ?>
      <!--label class="views-label-<?php print $field->class; ?>">
        <?php //print $field->label; 
		if($field->label == 'Nid') $nid = trim(strip_tags($field->content));
		?>:
      </label-->
    <?php endif; ?>
      <?php
      // $field->element_type is either SPAN or DIV depending upon whether or not
      // the field is a 'block' element type or 'inline' element type.
	  $path = htmlspecialchars(substr(htmlentities($field->content, ENT_QUOTES), strpos(htmlentities($field->content, ENT_QUOTES), 'http://')), ENT_NOQUOTES);
	  $path = preg_replace('/&amp;quot;/' , '', substr($path, 0,  strpos($path, 'alt')));
	  $path = substr($path, strpos($path, "/sites"));
	  if($field->label == 'Thumbnail'):
		  print l(html_entity_decode(theme_imagecache('image_316x176', $path)), "node/$nid", array(
			'html' => TRUE,
			'attributes' => array('title' => t('Go to the previous image.')),
		  ));
	  else:
      ?>
      <<?php print $field->element_type; ?> class="field-content"><?php print $field->content; ?></<?php print $field->element_type; ?>>
  </<?php print $field->inline_html;?>>
<?php 
		endif;
endforeach; ?>

This is a quick fix as video module is taking default image size settings.
But it would be great if we get imagecache preset for selection while setting format in view.

I am working on this. If anyone who already fixed this please update the patch here.
