Thanks for the reply. I have been struggling with 2 issues: 1) how to uninstall my current ivtv version 0.10.1 - using the package manager in Ubuntu, I only see ivtv-utils. Removing that package apparently does not remove the driver - 0.10.1 always loads on modprobe ivtv 2) how to install the driver from linuxtv.org. Once I unpack the tarball, I cd to /linux/drivers/media/video/ivtv and do make: "make: *** No targets. Stop." Unfortunately, there are no installation instructions in /linux/Documentation/video4linux/README.ivtv. Can you give me any pointers on uninstall/install? Thanks-
