Actually, I think the corporate firewall blocks port 554 (used by rtsp) or the rtsp protocol. So, I found the solution: using the 8080 port (used by http) or using the port 554 (used by rtsp).
Instead of the URL:
Code:
rtsp://212.54.100.33/video/DATA-2006-04-14-22-01.rm
use:
Code:
rtsp://212.54.100.33:8080/video/DATA-2006-04-14-22-01.rm
or
Code:
http://212.54.100.33:554/video/DATA-2006-04-14-22-01.rm
and it should work great!
