The constant-height Custom Anamorphic setting is used to maximise vertical resolution for playback on devices that support greater than 720p output (e.g. Mac/PC, ATV1, ATV3?, any other media player) while maintaining broad ATV compatibility.

the ATV1 didn't support greater than 720p, although it did upscale (apparently).
i had 2 ATV1's, and now 2 ATV2's.

It supported 1080p output, it just wouldn't play 1080p files. So if you gave it a 1330 x 720 file it would actually draw it as 1330 x 720 within a 1080p frame, rather than scaling it back down to 1280 x 688. The whole custom anamorphic idea began with the ATV1 when it enabled 1080p output.

It's kind of marginal when we're talking about 1.85:1, but if you start dealing with scope aspect ratios then it becomes more relevant, e.g. 1920 x 800 -> 1280 x 544 loses quite a lot of vertical resolution when compared to the 1280 x 720 blown out to 1692 x 720 that the ATV1 could do.

but irrelevant when dealing solely with an ATV2 ?
