^ What I meant by the untampered-with aspect ratios was that, before about early-mid 2010, rage would air letterboxed 4:3 videos in their original, intended aspect ratios. However, from that point onwards, such videos aired as though they were 16:9 being letterboxed to 4:3. So, for example, a letterboxed 4:3 video containing slim horizontal black bars would now be aired as though it was the 16:9 enlarged signal being squashed back into 4:3, with thicker horizontal bars. Before then, it would have aired with the original, thinner bars.

I know this as I used to ask someone I traded with who still recorded the analogue signal to grab some letterboxed 4:3 videos for me.
