There have been other discussions on this BBS about user-editing of the player's fonts. If you wish to edit the font files, please locate those discussions and see if you can get enough information to allow you to make any changes you like. Your complaint about the number 8 is one of the very first things I noticed when I got my player, but now I don't care about it at all and it doesn't bother me in the least.

Regarding the button on the remote: it is behaving as it was intended. Short press switches source, long press powers down. Note that you can also power down by holding the top button on the front panel. This isn't specifically in the FAQ, but it's in the Button Guide at www.riocar.org.
