Maybe a bit more RAM would help with the higher resolution?  I don't
know really.  We hardly ever watch LiveTV and when we do I still have
the direct (analog tuner) input to the TV.

I assume you're using (or at least have tried) 'Browse' mode, which
means that you can scroll quickly through the channels, seeing only
the guide data.  When you get to the channel you want you press OK and
the channel change takes effect.  You can enable it by default in the
frontend setup somewhere, or toggle it on and off with 'O'.
