I will try to explain that issue with more words like I want to say from the beginning I have a K-Lite Codec Pack 7.0.0 Full.
I am starting MC player and I am playing a video/audio file. After that I minimized the MC player and in Windows Explorer I start to look for audio video files which are on different folders or on different partition on the HDD (I have only two partition on my HDD) ... In one particularly moment I am trying to play a file... MC player load the file and everything is okay.... I minimized again the player and I am making some job on the computer... In the mean time I am deciding to play different file... MC player is running a file in that moment... I see file audio/video (doesn't matter witch) and I double click on the file with the mouse. For a bit of the second I see my cursor of the mouse loading but the file is not in MC player list... I am trying again to play the file... and everything is okay now... Again in a while MC is playing some files which are in the playing list... I see some file on the HDD I mark the file with the left click of the mouse and I press enter at the keyboard... I see again the cursor of the mouse loading but again the file is not loading in the MC list and after that is not playing...
First I was thinking after a while my HDD is going in sleep mode but it's not that because I had make a power plan in Windows for 'high performance' like I put for the HDD never to sleep...
Now I am thinking... what could be the reason for that, because is really annoying....
Any ideas ?
