Hello, once again I need your help.
heres is the link to the video

you will need Spain VPN, .f4m is encrypted, i used to use GetFLV to get .m3u8 trhough ipad kernel but nowadays they play a video ad (mp4) before load the streaming, since then i cant reach the .m3u8 again because the mp4 ad, some times once every 100 tries doesn't load the ad and i can get the stream, but rarely happens.
any help or tips?
thanks a lot.
