Glad to have helped.  I find myself in a situation sometimes of not 
knowing where to start looking.  Of course, sometimes knowing where to 
look doesn't always help either but it is worth a try at least.  I 
recently had video issues and knew where to look but the solution was 
not so obvious to me but someone with better googling skills found a 
solution.
