note that there are 7 flow video(the best is the 5th for the bitrate veri high and the resolution hd ready)
with wireshark,i have found the link of the first segment that is:

/ondemand/italy/vod/fifa2010/replaytv/fifa_live-isml/2010-06-11-11-49-37-040/segment001/fifa_live.ism/QualityLevels(350000)/Fragments(video=509800000000)

clearly i have found also the named server..and now the url is:

http://replaytv.rai.it/ondemand/ital...o=509800000000)

i have overwrite the qualitylevels parameter with the highest of the list in csm file and the link for the first segment is :

http://replaytv.rai.it/ondemand/ital...o=509800000000)

this operation must be repeated for all the segment audio and video...my problem is:how join all the segment to obtain a single file?and what is the codec used?wireshark classificate this segment files such as mp4 audio and mp4 video but if i open one of there don't function...can someone help me?

moreover i have read here
