School holidays are over! So I decided it was time to solve this problem. Effectively I mounted the dish on the polar mount and bingo! the twist of the dish was required to get a lock on the satelite. Now I just have a cable problem to solve - The dish is on the terrasse 15 metres away and the cable has to get to the PC. I don't want to live with a PC (even a silent one) in my bedroom... Cheers Tony PS I can document this with photos but I don't think the list permits that -- _______________________________________________ linux-dvb mailing list linux-dvb@xxxxxxxxxxx http://www.linuxtv.org/cgi-bin/mailman/listinfo/linux-dvb
