Hi - From: Selva Nair [EMAIL PROTECTED] But why do you care about top_field first when the source is progressive? I don't care which order the fields come in - could have been the DV standard's bottom first and I'd have been just as happy. If you use 24000:1001 and pulldown

Redhat 9.0 can be made to work with a DC10+ out of the box. After having problems compiling the zoran drivers I found that kudzu will find the DC10+ and then you can modprobe the right modules. I managed to get it to capture perfectly. Though thinking about it it wasn;t quite out of the box

Hi Laurent, It looks like you haven't configured your kernel tree (make config or make menuconfig). Odd, the kernel source tree is from the Mandrake kernel-source RPM, so i figured it had all that done already. When I get home, I will do the 'make menuconfig' and then the 'make dep', and see
