The memory behavior may or may not be normal, but you haven't really
given any information about mythtv's use of memory so it is hard to
tell.  You've attached a bunch of plots of system memory use, which
likely includes stuff like disk cache.

If you just played a bunch of video files using mplayer you could very
well see the same system memory behavior.

I don't understand why mythtv uses so much virtual memory in my
installation, but it is fairly harmless since virtual memory is free
(well, at least the first 256 TiB are on most CPUs).  Resident size is
the biggest area of concern, and that isn't too bad.
