I am in the process of converting my wmv-hd wmv/wma pro movies to mkv VC1/AC3. I have finally found the perfect wmv convertor, WMV Converter 0.33b. I have tried many, but they were limited, and at the very least, wouldn't keep 5.1 surround or had very bad quality and took way to long. This little tool the video stream is copied, left in tact, the audio stream is converted to AC3 640. Conversion is in one step, as fast as copying a WMV file. Perfect, only complaint, only does one movie at a time. I am trying to figure out if there is a way to batch the workflow for multiple movies. I cannot find the creator, and the webpage link is dead and gone. I was lucky enough to find the converter tool on usenet. What I do know is the tool is written in Delphi, no source code distribution. The developer made an updated version with commandline support, but I'm not sure if the version I have has it. If it does I have no idea how to make use of it. I would be glad to post the file, but don't want to break any rules. I can't remember if posting links are allowed here or not.
