"Realistically Insane" H.264 samples?

So, we're making good progress on the H.264 support for Silverlight we announced a ways back: While we've got a pretty big library of content for testing, I wanted to see if anyone had any particularly challenging or complex files that might be worth us testing. In particular, I don't have a lot of content with very complex multiple reference frame and pyramid B-frame patterns; our encodes allow for those things, but the sources we're using aren't triggering anything all that unusual. Is there any content out there anyone can suggest we take a look at?

Are you looking for 1080p@59.94fps 50MBps samples :) ?

There are a bunch of samples exhibiting various features and trickiness over at . There's also all of the official compliance testing streams. Here's a list of some I have (I don't know if I'm allowed to upload them or not). Code:

the killa sample might help, dont know where to find it though
