Excessive audio bitrate

Audio bitrates higher than 128kbps are rarely needed for internet streaming. Consider keeping the bitrate around 128kbps for optimal bandwidth usage.

VBR in use

Consider enabling CBR for improved stream quality. CBR will use a fixed bitrate which allows a smoother network stream, reducing the chances of frame drops for both you and your viewers.

Excessive bitrate

Your bitrate is very high. For live streaming, your viewers must also be able to download at the bitrate you specified. Setting too high of a bitrate will cause your viewers to experience lag and your stream may also drop frames if the streaming service you use does not support such high bitrates.

Hook conflict detected

Game capture detected a hook conflict but was unable to determine which application was responsible. Try closing any other applications that may be injecting into your game, such as FRAPS, D3DGear, MSI Afterburner, AMD Raptr / Gaming Evolved, Action!, TeamSpeak/Mumble Overlays or any other kind of FPS monitor or overlay program

All other activities is perfectly synced, except Youtube videos.

I am looking forward to any feedback.

Cheers.

Honestly it sounds like you should just get a browser addon and download the videos directly. If that's not an option, your log file shows that you set a 1000ms global audio offset. Have you tried returning that to 0?
