What up with Sony and having resolutions that are slightly off 16:9?

PSP has a native resolution of 480x272. If you shave off 2 vertical pixels it becomes 480x270 and is true 16:9. Same goes for the PS Vita. 960x544, shave off 4 vertical pixels and it becomes true 16:9. Is there something I'm missing here?

Multiples of 16. Good for alignment and many compression algorithms use that as blocksize.
