Actor has added herself to a series in which she didn't appear - how do I remove her?

In a nutshell: Actor has added herself to pretty much every episode of an Australian drama serial. I have over half of the series run on video, and she's not in any of 'em. Additionally, she's ranked herself as 1st in all of them, which is more than cheeky. 

I'm a fan of the series, watched it on first run and recorded most on VHS tape, and have never heard of her. She not in the opening credits, not listed as guest cast on the closing credits, not listed in any series publicity or program listings. In fact, the ONLY place where she's mentioned as being in the cast is IMDb.

I've gone through the correction process for the first three episodes, removing her and supplying a screen-cap of the closing creds showing her not listed on them. But, it's going to be an absolute chore doing that for every episode she's added herself to (386 in all), and this particular show only listed guest cast on the closers - if there was no guest cast at all, they just went straight to production crew, and I've no proof to upload.

Is there an easier way of having her removed?
