I can't imagine how he could still be running 8.2 or 9.2 software, as he stated in another thread,
but seems like that should be corrected before worrying about any other issue. Software that old must not have the fix for the sdv switching glitch that **you** were instrumental in getting Tivo to fix (and thanks again!).
