JWPlayer in Drupal has container ID starting with Numeric Character
While you're at it, here is a quick solution to it.

Since this is a fix for Drupal JWPlayer Module, do the following:-


Go to jw_player module folder and open theme folder.
Open jw_player.tpl.php and add the following line on top (probably where PHP declaration starts).



$html_id = "myvideo". $html_id;



It kinda does the job but I am sure you guys have better solutions than this. Please feel free to comment.

Found a better solution

Don't do upper suggestion. Paste the following code in jw_player.module instead.

Find this line $variables['html_id'] = md5(rand()); (I guess line 308) and uncomment it before pasting the following code instead.

while(1) {

      $variables['html_id'] = md5(rand());
      if (ctype_alpha(substr($variables['html_id'], 0, 1))) {
        //echo "First Digit is Alphabet";
        break;
      }

  }


Thanks.
