Since I know it might be next to impossible to watch big clips on Youku. It is for me.
I found the old files I downloaded in 2013. Merged 'em back to one file, and uploaded to mediafire.
So you can download it on mediafire here, instead of suffering on Youku:

It has chinese subtitles from melonpan subbers, but other than that, it's basically the same clip as the one I posted before.
