Has anyone else noticed that their Shield SP suddenly stopped catching the show? I have made a habit out of checking the TV listing each Sunday and this week I noticed that there were no Shields in my upcoming shows to record even though they were new shows. I deleted the SP, redid the SP and now I'm back in business w/ 2 shows showing up to record. I'm not sure if something changed w/ the SP or if my R10 is acting up. Can a SP become corrupt?
