Hi, lemon_1800 - I think u missed out my post in this forum.
anyway i will again reply it bez its very easy. -

I do know how to do it with Gomplayer. I use it now every day. I like Gomplayer better than any other player because it is easier to handle. Gomplayer also plays all file types. Preferences -- Others -- select All File Types and Codecs.

For making screen captures just right click on player for menu. There you see Control Panel (F7). Click CP or hit F7. With this little window you can make your screen captures. You can change the directory to where you want the screen captures will be safed.

To download this just click this link -

Dude, thanks for the reply. But I usually play videos in VLC player or windows media player, do you have any idea how to create screenshot from here?
