I must have set vlc to rotate the video at some time in the past.  I
almost never use it.  I just went into the video effects/geometry and it
seems that it was set to rotate the video permanently.  I changed the
rotation to 0 degrees and it is now playing properly.

This still leaves xine playing back without any video, but, then, xine
has been acting flaky on me for several weeks, now.  So I am willing to
blame xine for that, not the downloaded and merged file.
