Well, I managed to sit down and listen to the entire thing. I can't say I was terribly impressed with it, and got tired towards the end (probably shouldn't have done the entire thing in one sitting!). But I'm not convinced there's really anything of deep interest happening here [except for maybe some discussions about the Vampire Killer and Richter]. I got pretty confused in the 5th episode because of all this fighting going on.
I don't think the content of the story is anything to write home about - it doesn't sound like they have anything real dramatic happening, and it may be best to consider it as Iga playing around with other media, maybe getting people excited over the 360/PS3 game.
The basic story (kind of a recap) is that there is a vampire on the loose killing young girls in a village. Magnus accuses Alucard of the deed to Maria, who's mind becomes (unnecessarily) clouded by it. Silyl and Alexis, two vampire hunters, are on the scene trying to solve the problem, too, but seem to have been tricked by Magnus somewhere along the way. Lyudomil seems to have also been manipulated by Magnus over his beliefs about humans and vampires (related to Lisa's death). Richter comes out of hiding to help. Alucard and Richter fight Magnus in his lair and they kill him. Lyudomil dies, as does Silyl.
I think that Magnus's motive was to resurrect Dracula. I think he was using Lyudomil to help do it, but I don't know enough Japanese to figure out a whole lot. But what do I know? Maybe somebody (Danial? Raven-kun?) can give a better summary of the whole thing than what I have below...

[/UPDATE!]
So far, we've got a fairly detailed summary of episodes 1, 2, and 4 earlier in the thread, so I've linked to those. Here is my summary (along with links to previous posts), which undoubtedly has some errors in it:
Episode 1: Vampire attacks a girl, prologue (story recap with dialogue from SotN), Lyudomil discussing Lisa with Alucard (6:30), Maria and Alucard talk (8:30); Maria leaves in a fluster and Alucard leaves with his Imp familiar. [See Danial's post - #116 - for a detailed overview]
Episode 2: Silyl and Alexis are looking for the Vampire and wondering what happened to Richter, Maria is in town looking for ingredients to make a treat for Alucard (1:40); she gets a letter from Richter that talks about the vampire attacks and suspects Alucard of the deed (3:00); Silyl and Alexis run into Maria in the forest (4:30); they talk for awhile and then leave. Magnus appears and taunts Maria (5:35), accusing Alucard of killing the maidens (6:55); they fight, Maria gets caught in the incubus trap (10:15), but breaks free (11:10). Magnus flies away. [See #90 and #91 for a detailed overview]
Episode 3: Maria tells Alucard about Magnus, and she has doubts about Alucard; Meanwhile, Silyl and Alexis are in the forest and they kill a werewolf with holy water (1:40); Richter was watching the fight, and doesn't think they're good vampire hunters (3:00). Meanwhile, Alucard and Maria are talking again about Magnus (5:25), and Alucard gives her contrary information (basically confirming something that Magnus said). She runs off in a fluster (8:10) and Alucard goes out as well. Lyudomil and Alucard talk in the forest (8:40) and the topic of Lisa comes up again. Lyudomil leaves (10:55) and then Magnus appears (11:30). He taunts them (and I think he does something bad to Lyudomil) and uses black magic to choke Alucard and the Imp (12:30). He flies off, leaving Alucard all beat up. [See #96]
Episode 4: Maria is out looking for Alucard and runs into Alexis and Silyl (0:50). They talk about this 'medicine' and are off to use it, but Maria stops them and the vial crashes on the floor (2:50), releasing black magic. Richter comes to the rescue as Maria passes out (4:00). Richter and Alucard talk (4:15), then Maria wakes up (6:35). Alucard leaves and has a quick discussion with Richter (7:40), and his imp familiar tells him a vampire is near. [see Raven-Kun's detailed translation/summary #106].
Episode 5: This one was pretty confusing for me. Silyl meets up with Richter and says that Alexis has run off to fight Magnus; he runs off to help. Meanwhile, Alucard is in Magnus's lair (1:05). Alexis appears and confronts Alucard (1:30). Someone (either Lyudomil or Alucard) attacks Alexis. Lyudomil says some things that Alucard doesn't like. The Silyl appears and attacks with some holy water (3:50). Mangus shows up and it seems that Lyudomil might be aligned with Magnus now... The Imp gets attacked (5:45), and then Lyudomil (I think) beats up Silyl (6:15). Richter shows up (8:00) and Alucard disappears into another room. Magnus taunts Alucard some (9:00). Then Lyudomil says something about Lisa (10:15) and later on, Lyudomil seems to be morphing into some sort of monster (10:50). Magnus taunts, preparing for battle.
Episode 6: Richter fights some bats. Lyudomil continues to morph while Magnus taunts (0:25). Then Maria shows up (1:00) but gets attacked by magic (1:25). Alucard goes to her aid, and Lyudomil gets attacked by Magnus. Meanwhile, Silyl is dying, with Alexis and Richter by his side (3:15). Silyl suddenly realizes something important and tells it to Richter in his dying breath, Richter then proceeds to attack Mangus with the Vampire Killer (3:50). Alcuard and Richter fight Magnus, who is now unfocused. He gets sliced by Alucard and then dissolves into dust or bats (5:30). Alucard talks with his dying friend, Lyudomil (6:00). [See also #117]
