Question: I need to play videos on my drupal 6 site that would run well on IOS device (HTML5?).
Is such solution available?

My site currently serving flv files using jwplayer 6.x-1.1.

Answer: 
If you like to load the complete comment objects you can use this:

```
$result = db_select('comment')
  ->fields('comment', array('cid'))
  ->condition('nid', $node->nid, '=')
  ->execute();

$cids = $result->fetchCol();
$comments=comment_load_multiple($cids);

foreach($comments as $comment) {
  //do some stuff with the comment
  print $comment->comment_body ["und"][0] ["value"];
}

```
In Drupal 7 and onwards `comment_render` has been removed. Instead, you can load comments like this. 

```
$result = db_select('comment')
                  ->fields('comment', array('name','subject'))
                  ->condition('nid', $node->nid, '=')
                  ->execute()
                  ->fetchAssoc();
foreach($result as $comment) {
   print $comment;
 }

```
