I looked at the drop down that appears to the right of "New name" after selecting "enable file information field" on the "rename dialog", but I can't find an option to use some of the metadata fields of a WMV, like publisher and artist. Does the rename function support these metadatas?
{author} seems to get the Artist from a WMV file. (It's in the Documents category.)
I'm not sure there is a currently a way to get the Publisher tag (other than via a script which extracts it, or a 3rd party shell extension that provides a column for it).
Just an update in case anyone bumps into this question. It took me way too long, but I finally made a column for the publisher field. It is really simple, just use the method "DOpus.FSUtil.GetShellProperty" to query the PKEY "System.Media.Publisher". Works for MP4 too (I guess it works for all IDv3 files).
