Nice! Your modified script is much more better than my! I'm not a programmer, I know just a little bit. :P

Thanks!!....Another great IMDB script!!!

And need to add an include: http://us.imdb.com/title/tt*

Hi znerp!

I changed your script I don't like the abbreviations. So I replaced the 'hrs' and 'mins' abbreviations to the full hour - hours and minute - minutes words.
But this script is great!

Modified full script:

// ==UserScript==
// @name IMDB runtimes in hours and minutes (changed by Hiromacu)
// @namespace znerp
// @description Converts the runtime for films on IMDB from minutes into hours and minutes.
// @include http://www.imdb.com/title/tt*
// ==/UserScript==

infos = document.evaluate("//div[@id='tn15content']/div[@class='info']",
document,
null,
XPathResult.UNORDERED_NODE_SNAPSHOT_TYPE,
null)

for (i = infos.snapshotLength - 1; i >= 0; i--) {
if (/Runtime:/.test((time = infos.snapshotItem(i)).innerHTML)) {
time.innerHTML = time.innerHTML.replace(/(\d+) min/g, hourize);
break;
}
}

function hourize(str, p1, offset, s) {
var htxt;
var mtxt;
minutes = parseInt(p1)
hours = Math.floor(p1 / 60);
if (hours > 1) {
htxt = "hours";
}
else {
htxt = "hour";
}
minutes = p1 % 60;
if (minutes > 1) {
mtxt = "minutes";
}
else {
mtxt = "minute";
}
return (hours > 0 ? hours + " " + htxt+ ", " : "") + minutes + " " + mtxt;
}

Niccccce !
