John, thank you. You solved it. For the benefit of anyone else who may find these archives, I'll post what I did to fix this problem.
If you follow Jarod's instructions on how to make a custom boot image, you will apply the patch from his site. This patch neglects to copy over the ivtv_init_mpeg.bin file. To fix this, change the lines if [ -n "$USE_IVTVDEV" ]; then mkdir -p $MNTIMAGE/lib/modules cp /lib/modules/ivtv-fw*.bin $MNTIMAGE/lib/modules/ fi in the mkinitrd-ivtv file to if [ -n "$USE_IVTVDEV" ]; then mkdir -p $MNTIMAGE/lib/modules cp /lib/modules/ivtv*.bin $MNTIMAGE/lib/modules/ fi after applying the patch (or change the patch). Then rebuilt the boot image. That fixes it. Best regards, Daniel --- John Harvey <[EMAIL PROTECTED]> wrote: > Are you using a boot image built with mkinitrd?
