Are you a Windows 8 user having trouble viewing video files? Let me share an experience I have had. I use VLC media player to play my video files. It is an amazing piece of software that supports a vast array of video types. Recently a new Windows 8 update came around that rendered my VLC media player useless. I could watch video but with no sound. I tried other media players such as Windows Media Player, Quicktime, and DivX and encountered similar problems. Many experts suggest updating to the latest drivers for your hardware but I have a different approach. Try rolling back your drivers to a previous version. It worked for me! You can do this using Device Manager which can be found in the Control Panel. My sound driver is IDT High Definition Audio CODEC and I rolled it back to version 6.10.6417.0. Let me know in the comments about similar problems you have encountered.
