Solved
In the MP-->Cache-->Titanius Skin, there are a number of .png files containing different logos or icons.
Strangely enough, these .png icon "packages" are normally displayed as single image files, eg:
"packedgfx25.png"
Probably each of these .png packages are read as multiple images by...
Sorry where should I look?
In which .xml file?
the icon (red eye), has the name "unwatched.png", delete them all from the C drive
The Skin is Titanius, but I don't know where else to look to delete it
This is the icon (red eye) "unwatched.png"
that appears on the cover of each movies
Deleted from the entire C drive,
it is no longer in the skin cache, but it still appears in the movie list
Maybe some line in some .xml file needs to be changed,
but I don't know how
Update:
I tried the MultiShortcut plugin and it doesn't work,
MP still creates problems in the background, the only solution is to kill it from the taskbar.
I had created a .bat file with the instructions to launch the external player (JRiver) from MP, wait 6 seconds for the start of the movie...
Ok, I tried the MultiShortcut plugin,
I don't know if everything is installed correctly,
MP does not appear in the taskbar, but remains open in the background,
however I no longer have the problem of stuttering.
this is normal or has to be minimized in the taskbar ?
Thanks
