Hi,
I have a limited hardware to run mythtv and to use as my personal
computer, so I would like to configure mythtv with the minimal
configuration to use less memory and cpu.
When watch tv with Mythtv, sometimes image gets freeze and appears this
message "2007-04-10 07:30:02.629 NVP: prebuffering pause".
I am using a tuner without hardware encoder, just with hardware mpeg2
decoder so I am wondering if my hardware can handle mythtv and a usage
as Personal computer.
What is the lowest quality that Mythtv could run with my hardware and to
be possible to use another apps like firefox, openoffice, amarok?
Is it possible not to use software encoder when recording live tv or
pvr? Becouse if I record with raw format it could save cpu and memory
but I know it would generate bigger files, for me I prefer having bigger
files with less usage of cpu and memory.
I have noted and just running mythtv, I am getting into swap, but the
minimal requisites for memory is 256MB. Why mythtv is eating so many
memory?
I am using xfs in a small partition of 10Gb.
