Help a vidder out?

I've been compiling sources for a multifandom vid for Club Vivid, and for some reason I can't figure out, two episodes of Agent Carter refuse to convert for me and I can't get a usable copy that will work in Final Cut. I can convert every other episode I got from iTunes using Tune4Mac, but neither of these will work in a format that I can then convert for use in FC using MPEGStreamclip. Every single other episode works okay. I'm literally in tears, I'm so frustrated.

Would anyone have hi-res files, MP4 or .mov, of the episodes The Iron Ceiling and A Sin to Err? (That's episodes 5 and 6) WIthout any kind of logo? I really can't make this vid without at least Iron Ceiling, and all my source is hi-def so I hate to use a crappy .avi, even if I could find one. ETA: Thanks for the offers! I think I might have some coming from therienne that should work, but if not I'll be back!

Or if you know how to convert the files I could get using the latest version of Tune4Mac into something FCP will actually recognize, I'm listening! This has been the most frustrating experience. (And yes, I've tried re-downloading the episodes on iTunes, I've tried reboots, I've tried everything I can think of--nothing works.)
