Files that you are trying to play during the recording process behave different for every app you are using and also different in every player you are using. That means that recording file would not be played same in VLC player, Media Player Classic, FLV player etc. so the solution will be to try playing file in different players. Personally, I am using
portable version of 5 different players and Media Player Classic has been able to play most of the files. Further, depending of application you are using recorded file from same website will not be playable in the same player. Also, sometimes you have to refresh folder with file you are loading so the player could play it. Otherwise player see it as non playable file or unknown file format.
Cheers
