My system consist of two PC's, one Pentium 3 - 450Mc and the other a Pentium 4 
- 2.8 Mc. In the slow one I have two DVB cards , a Hauppauge Nexus-S and a 
Hauppauge Nova card. The reception of EUMETCAST is done via the Nexus-S card.
As far as I can see I have absolutly no problem in receiving the HRIT files. I 
use the DVBdata software from Hauppauge for setting the filters. With my 
second computer (in Linux) I try to process the HRIT pictures. The free 
software Sharity is used for mapping the hard disks from the slow PC ( in 
windows ) to the Linux system.

Trying to reverse engineer the software looks very difficult ....

Kind regards,
