I've got one of these players on order and I'm trying to find out about the size of video files.

For example: if I want to copy a 30 minute .vob file the file size is about 1.2gb. The player memory is 8 gb so I won't be able to get much video on it. I know I can add extra memory and that the player converts any (most?) formats itself. Is there any merit in using a conversion program before copying to reduce the file size?
Or have I got this all wrong?
