The version 0.7 driver that comes with the 2.4.9 kernel does not work with my DC10+ (in PAL mode) but I have had some time now to look at the source. The solution appears to be quite simple.
For those wanting to get the zoran 0.8 driver working on 2.4.9, you need to add a third argument to the call to video_register_device() in zoran.c. The integer value of -1 seems to be OK. Does anyone know the reason behind this change? Will this fix work for multiple cards?

Normally, I build the zoran 0.8 driver, but the build falls over like this:
zoran.c: In function `zr36057_init':
zoran.c:4260: too few arguments to function `video_register_device_R3a7ce584'
make[2]: *** [zoran.o] Error 1
make[2]: Leaving directory `/big/samba/Other/LinuxBits/Video/Current/zoran-driver-0.8'
So, I presume the interface has changed. However, looking at what IS provided in the 2.4.9 kernel, there is a driver zr36067 module that seems to take the same options/arguments as the zoran driver. The system logs indicate:

OK, so it appears to be an earlier 0.7 version of the driver, but I remember this used to work. The problem I am getting occurs when I try to use any tools, like xawtv, or lavrec:
Aug 29 11:36:34 gate kernel: DC10plus[0]: No bigphysarea_patch present, usage of high memory disabled,
Aug 29 11:36:34 gate kernel: DC10plus[0]: sorry, could not allocate V4L buffers of size 1280 KB.
Aug 29 11:36:34 gate kernel: DC10plus[0]: zoran_open: v4l_fbuffer_alloc failed
Now, I would have thought this big physarea facility would be in 2.4.9 by default. Is there anything I need to do to configure this kernel? Or where do I get this patch from? Or is the bigphysarea_patch error message a red herring? I reserve memory using [append=" quiet mem=505M"] in the lilo boot configuration, so it's not as if the memory isn't there.
Suggestions? Ed-T.
