Mark,
Have you tried AviSynth? Their site is at
Avisynth.org. This program is a frameserver. Here's how it works. After installed, you create a "frameserver script" in Notepad: simply a text file with the ".avs" extension. This file contains commands in the AviSynth script language, such as:
DirectShowSource("MyFile.WMV")
This avisynth script can be opened by programs that read AVI files, and as far as the app is concerned, it is opening an uncompressed AVI. This is because AviSynth decompresses the video and "serves" it to the application one frame at a time. You can drop your AVS file (remember, just a text file with the avs extension) onto your favorite media player and it will play as if it were a regular AVI. Other commands in your script can resize, cut, crop, edit, perform noise reduction, etc. Since Premere cannot open AVS files natively, there is a free plug-in that allows this function. I have not tried this with WMV files but I understand it does work. Unknown if this works on a file with DRM. Hope this helps!
