[mythtv] My MythTv Settings for P3 1000Mhz w 512 MB Ram

[Nathan Langley]

Here is my settings file.  Im running a P3 1000mhz with 512mb ram and a 120gb 
Seagate IV drive.  The drive tests to 38mbs/sec.
With these settings I can watch and record at the same time at about 50% cpu 
usage if I up the res to 480x480 I can record and watch at about 85%.

# Live TV options

# Size of the buffer for watching live tv, in GB

# The amount of space to fill the buffer up before
forcing an unpause, in MB
# Basically, the minimum amount of free space that the buffer will allow before
# forcing an unpause.

# Scale bitrate by frame size.  If this is set to 1, the target bitrate given
# above will be used as a guideline for 640x480.  Other resolutions will scale
# the target bitrate down according to the framesize.
