zoran driver problem

[meinnit]

Hi, trying desperatly to get some card working with VLC and failing!
This is more a linux module problem than vlc but....

I have a DC30+ miro card with a zoran chipset..
Apparently i need to use zr36067

with a fresh install of suse 10.2 zr36067 loads fine and with a little tweaking it kind of runs although vlc did crash quite quick. after a reboot zr36067 fails to load. This is not the first time i've come across this. It was the same an another motherboard with a via chipset. Some forums suggested that via was a waste of time so now i have an intel based board and the same happens. the errors seem to be around the i2c bus. Some relevent outputs are pasted below. Any help would be so cool as i'm about to loose the rest of my hair!!

Anybody shed any light?

I{m also having the same problem. The only tip I gotten around the web is to boot with these parameter this way:

acpi=off

but I found out I already have it off so I'm clueless about how to solve the problem.

I haven't check if I have an Intel board or a VIA board but in the 3 weeks that I been looking on the web for this problem I always read the VIA doesnt work with zoran cards.

Good luck !

I need it too

hey - thanks for your reply - i have made a little progress since. If i compile the kernel (did i make that sound like i know wat i'm doing?) with the i2c core support built in instead of modules. zr36067 AND all the others zr36016 and zr36050 all load according to lsmod.
Now there is a different problem it seems that the video device still isnt quite right. VLC reports that the chroma selection is unsupported but i left the chroma selection blank.
SO at the moment i am trying to figure out if the kernel compilation is correct and trying to figure out the correct module perameters. dmesg is also flooded with i2c info that doesnt tell me much.

i found this site helpful
http://www.linuxtv.org/v4lwiki/index.ph ... rnel_setup

and if you want any with the kernel let me know but i'm still making it up as go along!

i also found a windows xp driver for 10euros but thats a real last resort!

thanks again

let me know how you get on

hi, glad you're making progress, I havent, still searching. I'm trying to use an old Iomega Buz btw.

Hi,

I have a different problem. Same card - DC30plus on openSUSE 11.0

VLC (and lavrec for that matter) both fail while trying to open the device. dmesg tells me that there is no TV decoder loaded for the device and google searching on this brings up nothing useful (just code snippets of the Zoran driver).

lsmod gives:
