Here's the YouTube page links with the Elder Scrolls IV Oblivion machinima names below! Enjoy what's available so far for that's all there'll probably be once Skyrim is already released!
Mines: (Nancy McKeon in Oblivion)
While not the most popular (probably due to the lead character?)
11 episodes and only 1/2 of the 12th episode done so far

Look for Nancy McKeon in Oblivion
Egger3rd's TES-IV: Oblivion machinima series (OrcBlivion)
6 episodes done so far with hopes of a 7th episode

Look for OrcBlivion
RaditzTheRadish's KDMD and some other Oblivion machinima series

Look for KDMD
Kaiem's CNiO series (You should all know this one, but I won't type in what CNiO stands for due to the site's stance on the name)
10 episodes with now uknown news on the 11th episode
http://www.youtube.com/kaiem
(look under his playlists or favorites for (You know what))
Incogneatus (should I say more?) Oblivion machinima series known as Night Motherfathers
I think 2 or 3 episodes done so far with no word of if any more episodes will be done, but the series needs more Oblivion episodes as the series doesn't seem complete and still seems at at least midways thru the series storyline to me!

(look under his favorites or whatever on his page for Night Motherfathers)
I'll post links with the YouTube page of any other Elder Scrolls IV: Oblivion machinia series as I find them on YouTube!
I just hope the other Oblivion machinima directors ain't giving up on making new episodes for their Oblivion series due to Skyrim!
