[mythtv-users] liveTV sucking up CPU cycles?

[Yan Seiner]

Here's myth with liveTV:

  PID USER      PR  NI  VIRT  RES  SHR S %CPU %MEM    TIME+  COMMAND
19863 mythtv    20   0  682m 279m 125m S   66  4.7   6:43.18 mythfrontend
18477 root      20   0  123m  39m  26m R   26  0.7   2:48.89 Xorg


Here's myth playing the exact same show as a recording:

PID USER      PR  NI  VIRT  RES  SHR S %CPU %MEM    TIME+  COMMAND
19863 mythtv    20   0  694m 228m 125m S   32  3.8   0:46.36 mythfrontend
18477 root      20   0  115m  31m  21m S   19  0.5   0:14.58 Xorg

????

LiveTV uses 2 - 2.5 times the CPU cycles of playback.  I have no idea 
why....
