Striped video screen

[wzazza]

Hello,
I`m totally new to zoneminder and linux it self (so I have no idea at all with what to start in my problem). Somehow I managed to install zoneminder and added one camera (monitor), but when I try to view it, it`s showing striped black and white screen (see attached file).

I have Ubuntu 12.10; ZoneMinder: v1.25.0;
Video capturing card works as 4 separated video channels: /dev/video[0 to 3]
Could it be that this card is broken? Or is this something else.
I have no idea with what to start to fix this problem, could someone please help? If possible in some "zoneminder/linux for dummies" way. Thank you.

post the card model, the camera, and the settings you used when setting up the monitor. These will all be helpful for anyone who can answer. I don't have an analog setup right here to look at, but what you have seems to be a setting problem.

When runing "lspci" in terminal, it shows that the card is: Philips Semiconductors SAA7134/SAA7135HL Video Broadcast Decoder.
Bought the card from dealextreme: goo.gl/ddSx4
Cameras are also from DX: goo.gl/dIWwL and goo.gl/6nc9c
(sorry for links as text, as a new member to forum I cannot post full links yet).

Settings for monitor:
General
Source Type: local
Function: monitor
Enabled: [true]
Maximum FPS: 25.00
Reference Image Blend %ge: 7

Source
Device Path: /dev/video3, - also tried with video0, video1, video2
Capture Method: Video for linux version 2
Device Channel: 0
Device Format: PAL (tried also with NTSC)
Capture Palette: YUYV
Capture Width (pixels): 320
Capture Height (pixels): 240

I have not changed anything else.

I have just installed 'Cheese' to test what will this program output, and have the same striped screen. After what I`m now thinking that the problem maybe is not connected with zoneminder at all, but with video sources /dev/video[0to3]
Also there is no difference if there is cameras plugged in or not, the same striped screen or sometimes totally black screen shows up.

This is slowly killing me Could anyone please give some advice what this could be and how to fix it.

Unbelievably I fixed this.
Here`s the solution:
What I did is:
1) Opened for editing file (as root user): /etc/modprobe.d/saa7134.conf
2) Added this line:
options saa7134 card=33,33,33,33
3) saved and restarted computer.

And that's it, it works now.
