First of all I had some reason to make all regexps ungreedy, so you probably only need to have (.*) instead of (.*?) in the pattern.
But the real problem I would say is that your HTML part is 281 characters long. Both the Markup and HTML parts are limited to 255 characters, because I wanted to have the fields as VARCHAR in the database. I suppose I could change to TINYTEXT or something though if more people want to have long strings. I'm not sure how this affects speed and portability though, anyone has any ideas?
If you can trim the HTML part down 31 characters I guess that it would work. Don't know if that is possible though.
