#2582: buffer underflows ecoding HD video to ntsc-dvd

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:
{{{
