It looks like the info from nvidia-settings might not be completely
correct.  I'm getting a variety of resource errors from VDPAU when trying
to watch recordings:

2009-03-20 06:52:57.710 VDPAU Error: Error at util-vdpau.cpp:599 (#23, The
system does not have enough resources to complete the requested
 operation at this time.)

So, maybe it looks like the VRAM is there, but really not?  Normally, this
would be a BIOS setting to change how much is allocated, but there aren't 
BIOS in this bugger...  The total RAM reported by free (~874mb) suggests
that only 128mb has been carved out.

Other than getting another stick of memory, I'm not sure what I can do. 
Does anyone have any thoughts?

True.  I'm expecting that with 512mb of RAM, the mini should run a bit
better than my appletv which gets only 256mb after the VRAM is carved out.
 It might be moot if I have to get another stick of RAM, too.
