Program to remove links and other detritus from WMV files?

[Aikousha]

Recently we've been getting files to use in projects that are made with WMV. Unfortunately they contain links and other things internally, meant to spread viruses. This is the client's fault, but we can't overhaul their computer for them, and thankfully our IT dept. has security in place that automatically stops this. The problem is that the files are instantly quarantined, and unplayable.
We're looking to find out if there is a program that will strip the videos of the garbage without re-encoding anything.

Anyone made anything like this, yet?

Not that I'm aware of, offhand - but if the videos are immediately quarantined when anything tries to open them, wouldn't the security/antimalware measures do so when anything tries to strip the unwanted stuff out, too?

I'm not entirely sure how the IT guys have set-up that part... they've been getting more and more, "don't touch that stuff," on me. But, something in the last couple of things we got from this one client (720p in WMV?!?) opens IE, and then gets yanked (apparently trying to get past the firewall is what triggers the security), and the video window stays open, but doesn't play. As everything we have (including Macintosh stuff) uses system routines to view/transcode WMV, this happens no matter what I've tried. I don't usually work with windows, since the tools are better on Linux/Unix and Mac, but I got stuck with this anyway. I could put this on an isolated Mac and decode to raw/etc., but this typically takes 8hrs/30min, and locks up the processor until it's done.
If someone knows of a transcoder that can read (and not actually open to the system) in WMV9 and later, it's a solution, but we try not to recode anything more than we have to.
My guess about these videos is that the client actually has a virus which is inserting this stuff, but since I'm not allowed to interface with clients, there's no way to ask directly about this, without actually risking my job.

I wasn't completely sure, earlier, but it looks like asfbin may do the job. (I'm not sure if the GUI version is completely up-to-date, but you might prefer it to using the original command-line version. Not sure if the GUI version can do batch work, though.) I don't normally deal with ASF/WMV/WMA files with the embedded calls or other scripts, so I didn't know for sure when I replied, above.

Do the Flip4Mac components still allow the scripts and website calls to execute? Never did check that (never really bothered to play many Windows Media streams on my old iBook... )

(Edit: I don't know if it's just my browser or not, but it's displaying the I had after 'above', above, at the end of the post. Weird.)
