 Summary of the bug: Since upgrading to v1.0.5 (and now 1.0.6) I've been
 getting hundreds of buffer underflows converting my HD video to DVD
 format, specifically NTSC format. I don't do anything special to the video
 to encode them and even video I've successfully encoded before are giving
 underflows when before they encoded cleanly.

 How to reproduce:
 {{{
