Sadly, it appears that players to not resize using fixed increments, so the numbers in that table appear to be incorrect. Specifically, I placed a 480x270 video in the player that BC calls "Widescreen with Video Text List" which has a default player size of 480x215 for a default picture size of 302x170. So I added 178 and 45 to the picture width and height, respectively, making the player 658x315. But this size did not fit the larger videos, even though the aspect ratio (1.78:1) is the same as the default size picture's aspect ratio. So I did some trial-and-error experimenting and it appears that the correct size for that player, when playing video that is 480x270, is 762x318 (judging it by eye). I don't see what the relation is between those dimensions and the default dimensions, since they have different player aspect ratios. This came up in the context of an email exchange I'm having with Derek, of BC Tech Support, so once Derek finds the correct answer, I will gladly post it here. Until then, don't trust the table -- use trial and error instead, unfortunately.
