I recorded Minecraft on my laptop with DXTory. I have the full version. I made a 20 minute video and played it using Windows Media Player.
It began to play for about a minute and then stopped completely and a pop up came up saying "Windows Media Player encountered a problem while playing the file." I tried searching about the problem and I tried the option of "Web Help" which the pop up gave me. Neither gave me any answers on how to fix this.
