Yeah. Also we'd be hard pressed to find an msrle decoder that isn't
either ffmpeg, vlc or VfW

It might be necessary to do this same thing for more codecs. We only
tested msrle which was painful enough. I wouldn't be surprised if say
msvideo1 requires similar hacks. This patch is conservative until we
learn why VfW needs this.
