Thanks for getting the new logs, Aaron.  I had seen your comment before, 
but forgot to update the ticket status from infoneeded.

Out of curiosity, are you using nvidia drivers?  If so, which driver 
version?  What Playback Profile (or if using one of the standard example 
Playback Profile groups, which group)?

Mark Kendall may have an idea what's happening, but the line:

2011-04-17 12:26:18.147 MythPainter: 953 images not yet de-allocated.

probably shows the source of the memory leak.  Don't know what would be 
causing the Painter to keep images.  I know there was a problem with 
some nvidia driver versions that caused serious memory leaks when using 
certain video renderers (OpenGL?  or was it VDPAU? or maybe either?).

(And, to make it easier for someone to guess what's happening:
