How to avoid Widevine Media Optimizer

[apet]

In our case we use RTMPExplorer without problem.
But some movies required Widevine Media Optimizer. I tried many programs to avoid this plugin that work as wall for downloaders:
WM Recorder - it start recording with his browser, but output file is undefined, it play good only beginning video screen with logo of company, without sound, then the next scene is black screen. Converters not recognize output file. And recording is MPG instead of FLV, it cancelled automatically to 3.90 GB stopping with 1h and 10min. duration, then start new recording automatically and again to 1h and 10 min. duration and again and again new recordings. No way.
RTMPHelper - does not catch any changes, it seems it sleep! The worst ripper i know. I was hoping to it, because it work with our browser.
GetFLV - this is the program with all kinds of bugs! This project is forsaken from hundred years from the beginning without any changes. The only changes is requirements for new flash player version. It can't download files more then 900 MB. They will be corrupted if recording is big. And we can't record in RTMP Mode, because output file is dropping with slow motion video stream. Record in RTMP Mode is starting, but no luck. Movie is playing in slow motion. Video is slow down then audio.
StreamTransport - it does not supported from Windows 8 and the project is officially forsaken.

I am talking about place with Premium access.

So, is there method to avoid Widevine Media Optimizer?
I do not need capturing. I need Downloading.
