What do I have to do to get video? its a 4 port card and I have tried them all.

I currently do not have the room on one of my windows machines to run BTSpy

Now at the top there is a type 171 is the the card type? if so is there card type 171? I see in dmesg it sets the card to 0

Thanks

Jim

Can you give us some hints on the card? Does xawtv work on it? How many bt878 chips does it have? Where did you get it? Does it have a name?

It is very easy, when you are trying everything to get it to work, to leave something that you tried in place. For future searches, post what you did to get it working. (modprobe, and ZM settings) And congratulations!

well I did something and now i get no video (in xawtv or zone) something didnt save when I restarted my server. i want to not load Xwindows on it since i had everything working.

But I know it works so i will be playing with that today and then running my camera outside

I get this now when I run xawtv.

it says it can not from ym frame buffer device..

i will start there .. Could be something in my modprobe.conf file
