If anyone wants this to work on PMs- go to your Admin CP -> Plugin Manager -> Add New Plugin

product: YouTube URL Converter by BOP5

hook: private_insertpm_process

title: YouTube Fix - PMs

Exec. Order: 5

Set the php code to:

PHP Code:

if (strpos($pm['message'], "youtu.be"))
{  
  $find = "#youtu\.be/([\w-]+)#";
  $replace = "www.youtube.com/watch?v=$1";
  $pm['message'] = preg_replace($find, $replace, $pm['message']);
} 


Set ACTIVE to YES and hit "Save"
This will do the conversion in PMs too. I didn't make it an update because not everyone may want to do it with PMs. One day if I add options to this product I can make it something you may enable or disable.
