Okay, some good and bad news: Seems like it's a problem with the mencoder version used. (and not a bug in Hybrid or a general problem of mencoder)
using:
some versions produce garbage others don't.
-> try extracting mencoder.exe and mplayer.exe from https://www.videohelp.com/download/MPlay...0d113c8.7z and see whether that fixed the issue for you too
Cu Selur
Ps.: not sure whether this is due to a change in the ffmpeg libraries (which mencoder uses) some of mencoder dependencies or a bug in the build suite I use (https://github.com/m-ab-s/media-autobuild_suite).
