How to Encode old SWF with DRM into mp4s

I have a large product catalog with videos. All the videos were SWFs.

Now, I have to encode all the SWFs into mp4s so I can play them on my website.

I have about 700 files about 20 seconds long that have DRM on them for some stupid reason.

I had about the same amount without DRM and those converted just fine.

So the question...

Is there a way to encode the SWFs with DRM into anything different.

Thanks
