0b00 card sometimes black screen on moviechannels

Have 0b00 card (conax CD) and updated 008010,008011,008013 to 30/7-2012
but sometimes the picture is black on emotion,series and hits from time to time.
Anybody know a solution for this?

Picture is back again, BEFORE I removed my whitelist.
Will check again later if the channels works.

Thanks!

didnt work with delete the whitelist...
BUT I solved it anyway by checking options in oscan for my 0b00 card.
pincode = none
changed it to 1234 and picture is clear!
