[mythtv-users] Slowdown with higher res display

I recently moved from good old CRT TV to a 1600x1050 resolution LCD
that I'm using as a TV.  After the switch, I find that MythTV is
running a lot slower when switching between menu screen s.  Once the
video gets going, the performance is fine, but it takes forever to
move from the initial page to the list of recordings, or getting to
the DVD archive menu, for example.  During this time, I see it doing a
lot of disk activity.  I have a decent NVidia graphics card with 256
MB of on-board RAM so I don't think that is the problem.

My guess is that mythfrontend and/or X.org are now taking up a whole
lot of RAM because of the much higher resolution (2.2x more pixels)
and the system tends to thrash because I have only 512MB of RAM.  Is
my hunch correct or am I missing something?

If the RAM is the limiting factor, what choices do I have?  Increase
the RAM?  Is there any way to bring down the memory requirement
without having to reduce the resolution?  It bothers me that video
works fine but the static menus are so slow.
