It was OK in e.g. 24669 (latest official SVN) showing 60 Hz (windows) and 50 Hz (fps).

Same here - much worse than previous SVN.
Don't have logs for the moment but will post them later.

That version was querying the refresh rate from DirectX, which reports only in whole numbers, so even when the refresh rate would have been 59.xxx, it would most likely be reported as 60Hz.

As a first troubleshooting step you need to use PAL 50Hz refresh rate. When that requirement is met we can check the other things like running background plugins etc.

And when nothing else seems to help, we most likely have to state that MP 1.1.0 wont be able to play stutter free video on all PCs.

And please post the required logs

MediaPortal.log seems to be missing. But from the error log I'm able to see that at least HTPC info plugin is used. Please disable that and all other 3rd party plugins before testing again.

Oh, forgot to disable that one! Will come back later with all relevant logs!

Just a quick note, I'm currently testing a minor change to dshowhelper.dll's frame scheduling code. It might fix some dropped frames / juddering. But it wont cure badly behaving 3rd party plugins and I need to make sure it will work as good as the current SVN on on my dev PC.

my opinion is dropped frames back after that change
0002660: EVR presenter is causing stuttering when 25fps material played on 50Hz - MediaPortal Bugtracker or near it
becouse last time i created my own svn`s . After Scythe changes dropped frames become low( 1-2 in 5 mins)
but then its back again. now it ocurs randomly, i can look one channel without huge frame drop and leter get it after zapping back to that channel all later zapped channels with frame dropping too . I always use hdmi 60Hz in my setup.

There will always be playback issues on material where the source FPS wont match the target refresh rate. I wont even try to fix those as it is just mathematically impossibe to have judder free image from 50fps displayed on 60Hz.

Sure the current SVN could handle that situation worse than before, but it is not the main goal to make miracles happen.

The issue is when starting MP it gets to "caching graphics..." or Initializing strings.." and freezes with a MP critical error in the background...

the previous SVN worked great..

here are my logs for the ati htpc..

Please test without using Moving Pictures plugin (also clean the skin texture cache).
