I realise that not all of TVO's programming is in full HD (16:9) and they do letterbox occasionally. But all in all they have been broadcasting in 16:9 since they did the switch over to digital.

Until today apparently?

However, today (April 12, 2012) I tuned into a program that started at 19:00 and the aspect ratio seems to be 4:3 - no letterbox. It seems to be continuing to do this into the 20:00 programming

Is anyone else experiencing this? I checked TVO's website, and I cannot find any page that indicates they have discontinued broadcasting in 16:9
