Yep.  With X shared memory, you'll probably see this problem...

I'm guessing you're using a PVR-350 (otherwise, I can't imagine using X 
shared memory--unless you're doing it to "fix" the blue line, which, 
BTW, isn't a fix for it).  Therefore, you need to install a video driver 
that supports Xv (there is no "xv driver", per se).  For a PVR-350, this 
means you need to use John Harvey's ivtv X driver.  Search the lists for 
details on how to install/configure it.
