I came from Comcast too, maybe that's why it annoys me so much. I also liked how with Comcast if you were watching a DVR record and then switched to a live channel, the last button would take you back to the DVR record. Having to navigate back through the DVR menu in this instance is annoying.
In regards to the FiOS Idea Exchange, I got them to add native pass-through so I am happy about that. However, at the speed they roll out the IMG updates I won't see it until 2012. Maybe if I suggest this new functionality I will see it in 2014!
