Since both Bloodlines runs finish within nearly 5 seconds of each other, I decided to do a special encode which plays them side by side at the same time: RapidShare link (I don't own web space, sorry). Spear Dude's run on the left and Whip Guy's run on the right so naturally, I set up the audio channels that way; down-mixed their original audio to mono and then combined them to Stereo. This way, it'll be less of a mess to hear/see (not that it really is... Who am I kidding, yeah it is). I set this all up with AVISynth. This is the script I used:

A = UnalignedSplice(
\ AVISource("S1.avi"),
\ AVISource("S2.avi"), 
\ AVISource("S3.avi"), 
\ AVISource("S4.avi"), 
\ AVISource("S5.avi"), 
\ AVISource("S6.avi"), 
\ AVISource("S7.avi"), 
\ AVISource("S8.avi"))
\ .Trim(0,112684)

B = UnalignedSplice(
\ AVISource("W1.avi"), 
\ AVISource("W2.avi"), 
\ AVISource("W3.avi"), 
\ AVISource("W4.avi"), 
\ AVISource("W5.avi"), 
\ AVISource("W6.avi"), 
\ AVISource("W7.avi"), 
\ AVISource("W8.avi"))
\ .Trim(0,112172)

C = StackHorizontal(A,B)

D = KillVideo(A).ConvertToMono()
E = KillVideo(B).ConvertToMono()

F = MonoToStereo(D,E)

AudioDub(C,F)

I encoded this with X264 in MediaCoder but I didn't really emphasize on quality settings, not really my department (THE BACKGROUND IS MOVING, THE BACKGROUND IS MELTING). Maybe a proper encode is in order... I was going to YouTube-ize this but it looks bad even if I resize it myself. There seems to be some desyncs in audio/video when I play this back in Media Player Classic but everything else I've tried syncs fine (VirtualDub, Windows Media Player). I wonder if it's a rendering problem with MPC... Anyway, I thought it would be interesting to see both runs go head to head, frame for frame. It ended up being kind of neat, in my opinion.
