I've seen tons of threads regarding choppy playback, and regret having to post yet another choppyplayback question, but I havent' been able to resolve it from the FAQ and other thread sugestions I've seen thus far.
I riped the movie Act of Valor from blu ray to a MKV file using MakeMKV.
I then added it to XBMC and it played great.
MakeMKV does not recompress the movie and to save sapce I then recompressed it using FreeMake to a 1080p mkv file with 2 pass encoding.
This file plays fine in VLC and plays fine in XBMC in the background while I'm looking at the Menu.
However, when the movie is in fullscreen it really choppy and unwatchable.
I messed with the obvious setting like disabling fake fullscreen mode and scyn refresh rate to display etc.
When I turned on degbuging I notticed the fps were different in the 2 different modes.
In the background mode the fps was fixed at 100 and the image was smooth
In background mode the fps was fixed and the picture was smooth
In fullscreen mode the fps jumped all over the place between 30-60 and was never constant.
Why is the refresh rate different while the image is in fullscreen or if the image is in the background while the menu is visable?
I've tried checking and unchecking the sync video play and it doesn't seem to do anything.
My display is set to 1920x1080 fps 60p
I will get the log file and media info on the file tonight an post it as I know that will be helpfull.
the system XMBC is runnign on is a a new i7 3770S using the HD4000 integrated graphics, w 8G of ram.
Thanks for any help, and my apologies for the post if I missed something obvious that already posted.
