Thanks for the update.  I have been considering making the leap to .26 
just because of this bug.  As someone who has never built mythtv , how 
hard is that to accomplish? Is it possible to do a build of just that 
file and replace the file that is part of the atrpms package? For that 
matter could I take a version from someone elses system running the same 
kernel and just replace with that?
