I never trusted AR with my 9150 and always used to manually pad everything.
With the 2000T the auto-padding seems to work reasonably well, so far. I do have problems with unpadded AR.
I ALWAYS blame the broadcaster. I used to have problems with PDC and VCRs - a broadcaster problem. I had problems with a car radio and the RDS system - travel announcements not being turned off - a broadcaster problem. And don't get me started on aspect ratio problems - a broadcaster problem. I'd even go as far as to blame the broadcasters for the content!
