is it possible to make the script just "echo" the title (and settings) to yourself?

This is a masterpiece!
So far I'm loving it.

Anyway an option to match USER part for the hostmask would be nice.

in the "menu channel"> .Check every [x] minutes:{
var %c $$?="Enter time in seconds:"

I suggest to change from "minutes" to "seconds in the menu too.

Just checked this...again
Now, I modded this to "echo" the title to me.
The correct regex for the title is:

$regex(%yt,/<meta name="title" content="([^"]+)">/)

@Kibblz
you were right...there was a typo in the ratings regex.
(fixed in the previous comment, directly)

smsg $1 [1,0You0,4Tube]: $iif(%x >= 7,$4 $chr(124) $5 $6 $chr(124) $3 $chr(124) Views: $+(,$iif(%x == 9,$9,$8),) $chr(124) Rating: $iif(%x == 9,$+(,$7,) $+($chr(40),$8 $iif($8 == 1,rating,ratings),$chr(41),),$+(,Ratings were disabled,)),Either the video doesn't exist or it contained a malformed video ID.)

this smsg should fix the order

Still got some problems with Ratings regex.
Someone know "where" to parse Rating Value? How?
In the page source I cannot get "ratingL" anywhere...

EDIT

ehm, in the "ratings" regex, we're matching the word "ratings" after the value count:
$regex(%yt,/ratingL-(.+)"\stitle|"smallText">(.+)\sratings<\/span>/g)

Now, I'm from italy....the italian localization for "rating" is "voti".
So I've replaced 'ratings' with 'voti' and now, also ratings are parsed

Note, that even if in your browser you get the non-localized (en-US?) page, the socket from mIRC get your country localization.

on *:sockread:youtube: {
  var %yt | sockread %yt

  if ($regex(%yt,/<h1 >(.+)<\/h1>/)) sockmark youtube $addmark(youtube,Title: $+(,$regml(1),),62)
  elseif ($regex(%yt,/"length_seconds": "(\d+)/) ) sockmark youtube $addmark(youtube,Duration: $+(,$duration($regml(1)),),62)
  elseif ($regex(%yt,/ratingL-(.+)"\stitle|"smallText">(.+)\sratings<\/span>/g)) sockmark youtube $addmark(youtube,$+($regml(1),>,$regml(2)),62)
  elseif ($regex(%yt,/"watch-view-count">(.+)<\/span>\svi/)) sockmark youtube $addmark(youtube,$regml(1),62)
  elseif ($regex(%yt,date">(.+)<\/span>)) sockmark youtube $addmark(youtube,$+($chr(40),uploaded on $regml(1),$chr(41)),62)
  elseif ($regex(%yt,<a\sclass="url"\shref="\/user\/(\w+)")) sockmark youtube $addmark(youtube,By: $+(,$regml(1),),62)
}

This should work at the time of NOW.
Be aware that in some country, due to youtube's localization, something could not work as intended ;) (learn it the hard way...eehhe)

ohhh, wanna add this too:

on *:INPUT:#: {
  if ($regex($1,http\:\/\/.*youtube.*\/watch\?v=(.{11})&?.*)) {
    if (!$sock(youtube)) {
      noop $regex($strip($1-),http:\/\/.*youtube.*\/watch\?v=(.{11})&?.*)
      sockopen youtube www.youtube.com 80 | sockmark youtube $+(#,>,$regml(1))
    }
  }
}

this should "catch" also input from you, parsing youtube links that you paste in any channel.

Note that I'm a scripting beginner...so don't mind my "bad" style

EDIT: typo in ratings regex

heh...forgot to say that ip-adress.com, due to bots has a limit on queries per day.
registering a free account permit for 50 queries per day...so what about adding a "log-in" feature? eheh...ok...guess this' too much...

Yesterday I looked to your script to mod it for ip-adress, but I definitely suck at regex ;)

very nice snippet indeed.
Here's some other locators tools.
would be nice to have them all in one script only (selectable).
Here in Europe, seems the first two work better.
