Hello Mr. Stein!

I'm sorry, but the camera isn't an interlaced camera. The camera sends no
analog, but an digital videosignal and doesn't work in an interlaced
modus.

But perhaps that's the problem:

   332                /* trigger irq */
   333                if (irqs[board] & CR_TRIGINT)
   334                  {
   335                    ICP_IRQ_PRINTF("t");
   336                    switch (icp.opmode[board])
   337                      {
   338                      case ICP_OP_TRIGGER:
   339                        ICP_IRQ_PRINTF("T");
   340                        icp_splhigh (board);
   341                        if (cr_get_vbstat (board) == CR_OUT_VB)
   342                          {
   343                            if (cr_get_smstat (board) == CR_ILACE)
   344                              {
   345                                if (cr_get_fldstat (board) == CR_IN_ODD_FIELD)
   346                                  {
   347                                    cr_set_fldsel (board, CR_ODD_FIELD);
   348                                    cr_set_evbien (board, CR_DISABLE);
   349                                    cr_set_ovbien (board, CR_ENABLE);
   350                                  }
   351                                else
   352                                  {
   353                                    cr_set_fldsel (board, CR_EVEN_FIELD);
   354                                    cr_set_evbien (board, CR_ENABLE);
   355                                    cr_set_ovbien (board, CR_DISABLE);
   356                                  }
   357                              }
   358  #ifdef DEBUG_ICPCI
   359                            else
   360                              {
   361                                icp_irq_printf ("\nicpci[%c]: sample current "
   362                                                "field in VB?\n", 'W');
   363                              }
   364  #endif
   365                          }
   366                          icp_spllow (board);
   367                        cr_set_tmode (board,CR_DISABLE);
   368                        cr_set_acqmd (board, CR_SNAP);
   369                        icp.opmode[board] = ICP_OP_SNAP;
   370                      }
   371                  }

in line 343 in icpciMain.c you check whether the camera is in interlaced
modus or not (I think, you do). But the camera is not, and so there is
an error print to messages instead of doing something with the even/odd
fields as in line 345 - 356. Is it possible that the problem has
something to do with that?

Best regards
