same, im still have some probs whit Certain Codec..
I use, k-lite basic,,,, The Best one for me, cuz i dont want Media Player Classic.... i hate it.... and, ,, he have no Bugs in this one....
The K-Lite Codec Pack contains a tool called MediaInfo Lite. With that you can get a lot of useful information about a media file. For example what kind of audio and video format it contains.
See this link for more info !! :
****this link is only for help whit Codec, Nothing related whit ''VideoThumbnailsMaker''*****
So, i suppose , if we use this tool of k-lite, we will know what codec or Filter we need to Decode WMV Files.....
I hope i can help a little bit....
