Any ideea anyone, cause i would really hate to trow away two otherwise "good" cards ....

One thing i would try is research your card and check its being detected properly, ie if its autodetecting as a card=105 are you sure its a 105. Have you tried the usual 77?
Just my 2 pence mate and getting cards to work can be a 8astard!

Hello,

Try a few standard monitor resolutions. That is 640x480, 480x360, 320x240. Be sure to set all the monitor resolutions to the same resolution. Dont forget to restart zoneminder after making changes. Try varying the buffers say ... 20,5,10,10,1. Also check the shared memory max in sysctl.conf to approx 3/4 total memory .. ie kernel.shmmax=384000000 for 512K.

As James said it looks like you need card=77 in /etc/modprobe.conf.
