Recording MP4 RTSP streaming videos - Almost everything done but...

Hello, I?m trying to get some videos (MOV) from the following URLs:

rtsp://vstream.acm.org/AlanKay2004/AlanKay768k/AlanKayFull.mp4

rtsp://vstream.acm.org/10.1145/OOPSLA2005/1094855_768K/p11-ungar.mp4


I found this addresses throw the URLSnooper.

Well, everything was right until the time of testing the downloaded (with HiDownload 6.9 Beta 4) videos arrived..

When I try to playback the two downloaded videos, I only see a black screen, this happen with QuickTime player.

I tought that the problem could be this player, so i try with VLC and BSPlayer. But none worked.

The best result I got was with the BSPlayer, that played the videos but extremly fast and without sound.

Then I tought that the problem was my installed version of Quicktime, the one that I installed came with ITunes 6.0.5.20. I uninstalled this version, and install the QuickTime 7.0.3, which was the one denoted by the QuickTime agent in the HiDownload.
But this did not solve the problem.

I really hope that someone can help me, because i love to see this videos!!

I'm almost sure that I`m doing something wrong, so if it is something obvious I'm sorry for taking your time.

I say goodby from Argentina.
Claudio.
