Problem playing unDRMed WMV files with Western Digital HD TV after using fu4wm

Hi everybody!

I tried your step-by-step procedure and it seems to worked fine, but I have another version of IndivBox.key: 10.0.0.3646.
If I run FairUse4WM on my files, it will proceed them and generate an [NoDRM]_XXXX.AVI file. If I check this file with a rightclick, I can see that there is no "License" Dialogbox anymore. BUT if I try to play this movie on my "Western Digital HD TV" it starts for a few seconds and then it's end without any comment.
I want to do this on files from the german videoportal

Could you help me and let me know what I'm doing wrong?
Thanks, Alex

PS: Sorry for my english. hopefully you will understand what I mean... ;-)
