Automating Captcha form submission with Mechanize

[Dexty]

The idea is to automate download on o2tvseries. It's a website for film shows. We must automate the submission of a Captcha form in the process. The mechanize library helps with filling the form. Where we need to input the Captcha's content, Webdriver in Selenium helps with screenshotting and saving the Captcha picture locally. Meanwhile, Pytesseract helps with getting the picture's string for submission (about 75% accuracy).

The issue now is that after submission, a page with response Error: Captcha Does Not Match! is what I get even when the Captcha matches (it often does). A video file is supposed to be playing on the page after submission as that means everything is OK. I don't know if it's a cookie/sessions or Webdriver thing. Having a hard time getting the right Captcha input successfully submitted.
Here's the code:

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47 48 49 50 51 52 53 54 55 56 57 58 59 60 61 62

CAPTCHA technology authenticates that a real person is accessing the web content to block spammers and bots that try to automatically harvest email addresses or try to automatically sign up for access to websites, blogs or forums. CAPTCHA blocks automated systems, which can't read the distorted letters in the graphic.

Sounds like it is successfully doing its job.

Looks like I'm close with the code. And whatever is impeding the right Captcha inputs from being submitted isn't the Captcha itself, probably the Mechanize library or Selenium.
