[Metalab] solving chinese captcha

I'm working on rooting a camcorder and it would come in handy to have the datasheet of the SoC (Ambarella A2S70) . after some searching i found it hosted at baidu (http://wenku.baidu.com/view/6b4148ddc8d376eeaeaa3191.html?pn=50). but instead of browsing through it online (which is cumbersome) i would like to download it, which requires me to register. with the help of google translate i was almost there - but then the page challenged me to solve a captcha with chinese characters. -.- is there someone on this list able to solve the captcha for me? btw. there are credentials listed at bugmenot: http://bugmenot.com/view/wenku.baidu.com but i don't know if they work. thx, amir
