When I watch HD MKV's through MythVideo everything is fine for a few short minutes.<br><br>Then artefact's and stutter appear and this just gets worse until I stop play back.<br><br>This seemed odd to me, both as I have played HD content using other methods flawlessly, and because of the degregation (although I have no HD tuners so can't test HD MythTV recorded content).<br>
<br>So I loaded System Monitor and watched what happens.<br><br>When the video starts to play CPU usage goes to between 60% and 80%, outbound network traffic is near zero and inbound jumps up to 4mb and down to near zero in a stop start fashion.<br>
<br>However, slowly the outbound network traffic builds, eventually reaching a steady 4mb, at the same time CPU usage creeps up to 90% plus and thats when the stutter starts.<br><br>When I stop playback the outbound traffic falls slowly, taking a minute or two to fall back to near zero, whereas inbound traffic behaves as expected and falls to near zero as soon as play back is stopped.<br>
<br>When I watch recording made by MythTV everything works pretty much as expected, the one thing that does seem a little odd to me is CPU usage always sits at between 60% and 80% during playback of any kind (i.e. any bit rate), however outbound traffic does nothing in particular and inbound traffic arrives in a steady fashion rather than the stop start fashion when playing through MythVideo.<br>
<br>One difference between the two streams that might have something to do with this, is that the videos are directly accessible on a mounted share to the Frontend (in fact the only way I've been able to make it work) whereas the recorded TV is not and must be stream through backend.<br>
<br>I'm not at all sure what is going off, it's not I'm sure a network problem, I have a wired 1Gb network throughout. However, why so much outbound traffic when playing? And why the stop start nature of the incoming stream?<br>
