Advertisements Anyone else experiencing failed channel changes using IR blasters after the 9.1 update? I read through a few threads on 9.1 bugs, but didn't see anyone mention this. I have a 540 S2. Because of the digital cable box, I've been using IR blasters for ~3 years to change channels. I noticed that starting the day of my upgrade to 9.1, the TiVo is missing ~2/3 of its channel changes. Kinda ticked me off, 'cause I was out of town for a few days and with the new fall TV on, I missed quite a few programs. So, I re-ran the channel-changing setup and it performed flawlessly during the setup tests. So I let it go for a couple of days, and its STILL missing ~2/3 of the channel changes. It doesn't appear to be exclusive to any particular channels. Anyone else? I guess I'll call TiVo support this weekend and try to work it out with them...but if I can't get this fixed, this thing becomes a doorstop.
