code page

"type": "RaiTv Media Video Item",
"itemId": "ContentItem-3cf0b38d-7d01-4e46-b665-c9dc990622d6",
"weblink": "http://www.rai.tv/dl/RaiTV/programmi/media/ContentItem-3cf0b38d-7d01-4e46-b665-c9dc990622d6.html",
"mediaUri": "http://mediapolisvod.rai.it/relinker/relinkerServlet.htm?cont=DmssSlashBKGjiUrUeeqqEEqu al",
"h264": "",
"m3u8": "",

copy this

http://mediapolisvod.rai.it/relinker/relinkerServlet.htm?cont=DmssSlashBKGjiUrUeeqqEEqu al

and after this comes out

mediaSource="http://originsmoothreplay.rai.it/csm_nrp/raidue/IsolaDeiFamosi_2012/IsolaDeiFamosi_2012_PUNTATE/785293.csm"

I have already downloaded many times with Media Catcher (format. mkv), but not seen the video, and can be downloaded in. mp4?

thanks
