Anyone know anything about Cerious ThumbsPlus??

I have version 7.  When I use “Auto Clip Save” with animation files (avi, mp4) I get images created that are black.  Cannot figure out why???  Anyone do this and/or know how to cure the problem? 

I have WinDVD but it will not allow copying movie clips except with DVD files.

I found the problem.  I had loaded a codec some time ago that was being used by Thumbs plus instead of their standard codec.  But, their standard codec won’t play mp4 or flv video’s.
