Asalamu Alaikum Bro Sis,
I'll try makin a How To tutorial article regarding ummahfilms subtitling.
The article will be divided into sections i.e:
1. Getting the video from youtube
2. Using the video converter (Super)
3. Using the subtitle editor (subtitle workshop/DivX Land Media Subtitler)
4. Publishing video to youtube
Makin these tutorial will cost me significant time (esp. step 2,3,4), so be patient bro /sis, i'll do my best Insha Allah. I'll set my target at the end of this month.
But for the easy part (first section), all you need to do is this.

GETTING THE VIDEO
1. Browse the video at youtube, e.g : http://www.youtube.com/watch?v=3o6kpCLDMVg which is the url for the 1st vlog (funny things at jummah) in english version.
2. Add "kiss" just before the "youtube" part of the url, similar to this http://www.kissyoutube.com/watch?v=3o6kpCLDMVg and then TADA! you'll get a link for downloading the video directly.
3. Note that the video format is an .flv (flash video), to play it you need an flvplayer (get it here it's free and also notice that you need to complete some requirements to run this software)
4. That's it, you have the video and the player now

Hope this tip useful for you
