I have duplicate videobufs. They all seemed to have been touched at the same time. I've tried "sudo rm -rf /lib/modules/uname -r/kernel/drivers/media/*" before instaling and the result is still the same.

try remove staging media modules before install (see install.sh script) sudo rm -r -f /lib/modules/$(uname -r)/kernel/drivers/staging/media

Thanks that helped. I'm using a build system and then use checkinstall to build a debian package. It would be helpful to integrate those in the Makefile otherwise people like will be skipping Important steps.
