If you have recently begun to experience issues with .wmv file playback on EasyWorship, you may be using a special type of .wmv file that utilizes a video decoder called VC-1.
This VC-1 decoder is different from the standard WMV2 decoder found in standard .wmv files.
At present, we have found that installing the latest edition of the K-lite codec pack will work around the issue.
If you would like to try installing K-lite, you can find the download here.
If this does not fix your issue with WMV video playback, please contact our support desk.
