As others have noted, bitrate determines file size. However, if your new 
player can't play 480x480, perhaps it can play 352x480. Since 352x480 is a 
standard DVD resolution, it's likely to be able to work fine as long as it 
can recognize whatever type of disc format you wrap it in. (SVCD, CVD, DVD)

Read today's Resolution thread for more info on the issue. :)
