a little trick in NetTransport to take in account:

when adding new download, click "other settings" at right down corner, go to Streaming tab, under MMS section,set user agent to
Code:
WMPlayer/12.0.7601.17514 guid/3300AD50-2C39-46C0-AE0A-8BF52187E2C6
, click ok. you should get 2 download job, one with a size of 1.29MB or something and other with higher than 100MB in size! 

check the screenshot to confirm.



Normally, if you dont do this trick, the download process loops at downloading of "Ads" with size of 1,29 MB.
