Hi

i brought a PV155 16 port card from you,
we have just installed it into our zone minder system and are having alittle bit of a problem getting it to work as it should
system is running kernel as follows

Linux 2.6.22.5-49.fc6 #1 SMP Thu Aug 30 13:28:55 EDT 2007 i686 athlon i386 GNU/Linux
running on fedora 6

we have connected cameras to DB1 on blue V1-V4 and green V1-V4 and on DB2 Green V1-2
system seems /dev/video /dev/video1 to 3
see below for the grep output

when we select the source and channel in zone minder we have found the following

Video0 was working but it has now gone to blue screen output only, we have all cameras on 2fps caps

video0
red ch 0-3

video1
ch0 working
ch1 working
ch3 orange blue screen
ch2 orange blue screen

video2
ch0 ornage blue screen
ch1 ornage blue screen
ch2 ornage blue screen
ch3 ornage blue screen

video3
ch0 ch1 work
ch2 orange blue screen
ch3 orange blue screen

orange & red where zone minder shows camera colours for soruce

i have added to modprobe.conf
options bttv card=77,77,77,77

before i added this i could not see past ch 0 - 1 with black screens on ch 2-3 for videos where now we get blue screens

i noticed in the messages log when adding a deivce on video0, any chanel we get

I just worked this one out last night, thanks to some posts on the forum.

It's a shoddy numbering system on the card. Vid1- Green or Blue plugs on either adapter is Cam1 on each channel.

Example.

Video0(0) Vid1 Green
Video1(0) Vid1 Blue
Video2(0) Vid1 Green
Video3(0) Vid1 Blue

Get the picture? I lost about 5 hours trying to work out what was going wrong and why two cameras refused to give an image. Now it works like a charm!.

Although, now I see it laid out like this it isn't too bad. Could do with a little (WATCH OUT!) note on the docs though.
