Hello, I am using an HP envy M4 here in the US. Its an intel core i7 2.20 ghz, 8 gb ram running windows 8 64 bit. The recorded videos are saved to the computer in an avi file format but will not play in the avs player, vlc, windows media player, etc. I have also tried converting the videos but they give me an error at about 80% The files are very large like between 24-70 gb. I MUST get these videos working, PLEASE HELP.
