I've seen this occur a lot and I'm nearly positive it has to do with having 2 TiVos in one room. I'll be watching one TiVo and switch over to the other one and I'll see a "Can I change channels" banner on the other TiVo. What's wrong with this is that the TiVo already changed the channel (I've seen it 15 minutes after the channel change). Pressing "okay" clears the banner without any ill affects. What appears to be happening is that the 2nd TiVo puts up the warning, but using the 1st TiVo (since both TiVos see remote presses) causes the warning banner not to close itself when the channel changes. This is similar to the issue where using the remote for one TiVo will cause the 2nd TiVo to not time out of the menus (it treats using the 1st TiVo as activity on the 2nd TiVo). It's not harmful, but it is confusing and should probably be fixed.
