I feel Im so close... I have ZM running, I now have all 8 video inputs showing, I have a feeling I might have missed a setting somewhere as the picture stream is scrambled as if Im running on NTSC instead of PAL.

The attached picture shows what Im getting.. its moving video but just garbled.... I think I have the card set up correct as it came with the config to add so the card can work..

So close, but so far :)

If you are sure you have NTSC/PAL set properly then the next thing to do is to disable V4L_MULTI_BUFFER under options.

If that doesn't do it, then you need to re-verify you have the driver for your card configured properly.
The bttv driver, for example, will not autodetect your hardware. You have to insert a config file under modprobe.d to get it to work with your hardware.

I had a similar issue when I had "Rotate 90*" selected instead of "Rotate 180*"... it striped the video in a cascade similar to that

Ill take a look at both of those thanks.... the really weird thing is, I have a Zoneminder livecd from years ago... ZM 1.22.1 running on a 2006 Mandrake and it works great!!

I tried comparing the settings but its just crazy.

One other thing is, if I reboot, I lose the Video0 to Video7 from /devs/ sometimes it takes up to 3 reboots to get them back.. its like the card sometimes gets "seen" and other times the pc starts and completely misses it.

Sure is crazy, as I need to rely on the cameras working Im running another pc with win8 on and other software until this becomes stable...

PCI card? I remember back in the "olden days" some legacy PCI cards would not soft reset at reboot, required a hard power-reset to make them reset. Some BIOS vendors have had an option to send resets to the PCI bus, might be worth checking.
