Transcoder error on certain files

I'm having issues Transcoding a few episodes.  Direct Play works fine.  I'm on PMS 0.9.8.8 on Ubuntu 12.04, and when I try to stream/transcode these particular episodes, the Plex log spits out:

Oct 23, 2013 18:18:42 [0x7fecbdffb700] ERROR - [Transcoder] Failed to open bitstream filter h264_mp4toannexb for stream 0 with codec cop

I've attached the mediainfo output of one of these files.
