most of the videos and anime on my laptop are in avi or mkv format. anyone know a good software program i can use to extract part of the audio from them (by specifying the video time). i also have a few high res HD videos. how do i take a high res screen shot when the video is paused at a particular frame? if i hit prnt scrn and paste to a regular photo editor, it just pastes a blank screen. i currently have vista, mpc, vlc, paint.net and adobe photoshop.
