Over the last couple of weeks, I've noticed some quirky changes in the guide....
When returning to the guide from a playing channel, the guide will first open to the last time the guide was displayed, and then jump to update to the current time. I don't remember this being the case. When this happens, it also appears that some guide rows aren't correctly updated until the guide is scrolled (the top 'time' markers change, but the rows are off by I think the interval to the previous guide time).
It appears that the guide is having trouble dealing with shows that don't start on an even interval (many channels now have start times like '8:42' or '8:06'). When this occurs on the leftmost guide entry, it doesn't display anything in the first guide start time, instead of the previous show. There is a black block where the previous show data should be.
Just passing this on in case it's related to some of the other guide problems I've seen reported.
