first let get the trailer on the page
http://www.imdb.com/title/tt0413300/trailers-screenplay-E28048-10-2
(it is the spiderman - 3 trailer.)
When the page loads, open the page html source and look for
<iframe src="
here after src, there is /rg/TITLETRA_SCRPLY/wmp-300k/. Pass this. Then after this text come the page that contains te trailer.
http://www.totaleclips.com/player/player.aspx?custid=102&clipid=E28048&bitrateid=10&playerid=33&formatid=2
Paste this link (in this stuation the link is : http://www.totaleclips.com/player/player.aspx?custid=102&clipid=E28048&bitrateid=10&playerid=33&formatid=2 )
to an internet explorer. When the new page opens, then again open its page source.
NOTE: If you see characters like %26 vs , the first %.. is ?, then the others are &. change them
In this source, look for:
<PARAM NAME="FileName" VALUE="
or
<PARAM NAME="URL" VALUE="
The link after the value=" is the asx or ram file, which contains the link of the trailer.
In this case it is the asx file. and the link is :
http://www.totaleclips.com/Player/Bounce.aspx?eclipid=e28048&bitrateid=10&vendorid=102&affiliateId=
Paste this link to a web downloader program like flash get.
after the download when you look inside the file you downloaded, you must see file which begins with "mms", "pnm", "rtsp"
Usually you use mms or rtsp link.
In this case, inside the downloaded file (e280483t.asx):
<ASX VERSION="3.0">
<ENTRY>
<REF
HREF="mms://a1491.v264199.c26419.g.vm.akamaistream.net/7/1491/26419/v0001/screenplay1.download.akamai.com/26417/streaming/280/e280483t.asf?eclipid=e28048&bitrateid=10&vendorid=102&affiliateId="
/>
</ENTRY>
</ASX>
link. So paste this link to a web downloader program.
That is it.
if your web downloader do not support streaming media, then try mplayer.
on command line write this
pathtomplayerexe\mplayer.exe -dumpstream <strem_url> -dumpfile <local_path_to_file_to_be_wanted>
if you cant see the downloaded file, look to your home directory.
On windows it is "c:\document and settings\your_user_name\"
P.S: Soon this will be implemented in Download Trailers V.2, or somebody may help ;)
