And I wasn't aware of Google.co.uk. I'll update and good thinking on the integer only. Thanks.

I looked at this for another 10 mins and think that this should do the trick for both expressions:

PHP Code:

$viper_patterns = array(
    '#\[youtube\]http://(www.youtube|youtube).com/watch\?v=([\w]+)(.*?)\[/youtube\]#si',
    '#\[gvideo\]http://video\.google\.([^/]*?)/videoplay\?docid=([\d\-]+)(.*?)\[/gvideo\]#si',
);

$viper_replacements = array(
    '[YOUTUBE]$2[/YOUTUBE]',
    '[GVIDEO]$2[/GVIDEO]',
); 


I spotted that if you preview a post the text in the editor window gets edited too which isn't ideal I guess. I wonder if there's a way of preventing that from happening?
