Thanks for all your input.  Perhaps I better start using FFmpeg.  A
lot of my encodes use x264 AVC in FLVs to be played via an embedded
Flash player in HTML.  Also, I notice from the programmers of MEncoder
here in the mailing list, stating that it has "not been maintained for
years".  When was the month and year it stopped please?  I'm just
curious.
