Is Posterous video conversion broken?

Is anyone else having trouble getting Posterous to successfully convert their application video? We've tried uploading .m4v, .mp4, .mov (h264) and .wmv with no luck (we've waited over a day for the conversion to happen, and all have either failed or are still "in progress").

Obviously, the video is still playable if you click the download link, but it feels like that's a pretty bad experience and I'd love to have it in the flash player like the example videos (for example: http://dsiroker-private.posterous.com/private/FCAGetIemw).
