Thanks, I may try that.  I didn't really have an overriding reason to 
upgrade to V4L2 other than I was getting some kernel oopses sometimes 
during recordings or at the end of one but I think I may have addressed 
that by recreating my swap space which might have gotten messed up 
during a power outage.
