[mythtv-users] Recompiling glibc with optimizations reduces Mythtv's cpu usage.

[roger]

I just found out, Mythtv likes to reset my /sys interlace variable to 0
(deactivating interlacing) as "Live TV" is about to be played.

>From briefly looking over the Mythtv gui settings, there is no setting
for activating interlacing.  A user can only activate Deinterlacing
within the menus.

I need Mythtv to either: 
a) keep interlacing enabled or 
b) include a setting to enable it.

> Another option I have, activating interlacing on my device:
> # echo 1 > /sys/class/pvrusb2/sn-7435104/ctl_interlace/cur_val
> 
> At this point, I'm seeing Mythtv's cpu usage further drop down to an
> overall ~30-48%.  (Top shows mythfronted drop to ~20%.)
> 
> (One reason I'm seeing an additional 20% cpu spike every 5 seconds is
> due to gkrellm2.)
