Since TiVo pushed the .oM update, my S3 648250 OLED has not completed GC every other day to 3 days, as it did before the push. And this is with the tuning adapter turned off for 4 hours daily. I started seeing the running out of guide data message on Saturday 12Oct13. I left the tuning adapter off for 6 hours; GC still did not complete. Last night I unplugged the tuning adapter at 10pm (PST) and finally GC completed this morning around 6am (PST).
