I don't know what the issue is but hopefully one of you can help me solve this, hopefully it's something simple? I record a lot of video of my son using my camera on my phone and also on my camera using it's recording feature. Every time I try to play the videos in Windows Media Player Classic I get the error message below. It happens on pretty much all of them, everyone I tried so far at least. It comes up several times, I have to keep hitting the ENTER button then it finally goes away. Sometimes the video will play after that sometimes it wont. If I try to play them in Windows Media Player, nothing happens, I can hear sound but the picture is frozen? These videos have worked before so I'm guessing it's a codec that I have maybe installed over time, I'm not too good with computers so I might have installed something one too many times. I have both K-Lite Mega Codec Pack v8.6.0 Mega and 64-bit codec packages installed, I just left the settings as is when installing. Hopefully someone can tell me how to fix this as these videos are extremely important. Thanks for your time and help, greatly appreciated! EDIT: When I try playing these videos in VLC Media Player I get this error below. I hear sound but just see a black screen?
