* The 2021 rebroadcast is at 1920x1080i, compared to 1440x1080i
* The 2021 rebroadcast is at a much lower video bitrate; 4.472 vs 15.7Mbps (2.0G overall vs 6.79G). The codec / encoding parameters will have been changed (multiple times) over the intervening years; the newer encoding might not be as accurate, but is certainly much more efficient.
* The channel logos are different, but more or less equally ignorable. The 2007 "BBC HD" DOG is smaller but less transparent than the 2021 "BBC Four" DOG.
* The 2021 rebroadcast / main audio is DD 2.0 @ 192kbps compared to DD 5.1 @ 384kbps; however in the the 2007 broadcast the surround and centre channels are silent (so that broadcast was effectively 2.0 with an unnecessarily high bitrate)
* The 2021 rebroadcast is not identical; although I cut the start of the video to line up with the 2007 version, by the 14 minute mark the video streams are 10 frames off. I didn't check any further; the overall programme is 2 seconds longer in the 2021 broadcast / edit.
