MPUI player a standard player for media players is suddenly not playing. When a file is loaded , it usually starts another application mplayer.exe which it suddenly reports as not able to start , even though it is available in the same folder. The error message.. command line: "C:\Program Files (x86)\Mediacoder\MediaCoder -4399E\codecs\mplayer.exe" -nogui -noconsolecontrols -slave -identify -noquiet -nofs -term-osd-esc "[Fenny8248] " -hr-mp3-seek -subalign 1 -spualign 1 -sub-fuzziness 1 -subfont-autoscale 2 -subfont-osd-scale 4.8 -subfont-text-scale 4.5 -subfont-outline 2 -subfont-blur 2 -priority abovenormal -softvol -softvol-max 1000 -double -nofontconfig -font C:\Windows\Fonts\arial.ttf -vo direct3d, -vf-add eq2 -autoq 10 -vf-add pp -subcp CP1252 -monitoraspect 800:600 -subpos 96 -vf-add screenshot C:\Users\Public\Desktop\SAMPLE.avi Error 123 while starting MPlayer: The filename, directory name, or volume label syntax is incorrect. ******* I am doubly user the exe exists in the folder it exists , and the error is being caused by Windows because it was running fine earlier. I tried changing the folder name , reinstalling etc ,but still it is stalled. Any help is appreciated. Thanks.
