Security updated - Can't get mp4 url anymore. Please help

[Daigo]

Biezom kindly showed me how to find the mp4 url by turning off flash on Chrome, a few months ago.
Unfortunately the security seems to have been updated and the mp4 url isn't showing up anymore.

I can still get the .ts stream from the master m3u8 using livestreamer but would prefer the mp4 as it's higher quality.

Can anyone tell me how (or even if) the direct mp4 url can be found for this ?

Many thanks in advance.
