[linux-dvb] Mantis VP-2040 problems

Hi again. After adding the correct pci id's I thought I had my 
AD-CP400's up and running. I don't have dvb-c at home but scan seemed to 
work and just exited after failing to find anything. But when I 
delivered the machine to my friend with cable tv, scan crashes (tried 
several mantis hg versions). Any ideas? Are there differences between 
this card and the Cinergy C that some people seem to have up and running?
