[QUOTE="KevinM, post: 155070, member: 50013"] I really like MP but it's still a case of "so near but not quite there" with quite a few outstanding issues to solve. I run TV Server with latest SVN in a single-seat setup (with occasional multiseat use). Anyway, thought people might be interested to know of a very minor (and embarrassingly simple) change that I have recently made to my setup that has improved TV and video/DVD playback considerably. I have played around with various decoders, audio renderers (including reclock), and all sorts of settings to get rid of those minor stutters that occur periodically - particularly noticeable on News channel scrolling text messages. I've also turned off various Windows services to minimize the number of processes running. Mostly, this has failed to make any real difference. Finally, I dug up a copy of Process Explorer and left it monitoring CPU usage while MediaPortal was playing TV, and this showed up something quite interesting :- [IMG]http://www.millican.f2s.com/mediaportal/mp-normal-priority-cpu-usage.gif[/IMG] Now there's nothing running on my system that normally spikes like this when MP isn't playing TV or video. Out of interest, I changed the MP Priority setting in the MediaPortal setup from 'Normal' to 'High' and repeated the exercise. Would you believe it ? - the CPU usage profile now looks like this :- [IMG]http://www.millican.f2s.com/mediaportal/mp-high-priority-cpu-usage.gif[/IMG] Better still - the video stutter that I was getting a few times a minute has disappeared and those scrolling text messages in live TV news are completely smooth :) Shift-! now shows 0 jitter and no lost frames. Not sure if there is any downside to this yet, but it has certainly made a positive difference on my system. [/QUOTE]
