I have posted answers to these questions before, so you SHOULD browse the forums before asking again, but I will be nice and answer again. The Wii does read DVD-r and +R, no real difference in which is better or worse. Get a disc with good dark ink, it will last longer through time. Yes, burned games WILL wear down your lense faster. This is because they are constantly correcting for errors that are made when burning... the disc is written while it is spinning, errors are natural. The faster the burn (e.g. 8x is faster than 4x) the more erros will come up. think of it this way... what is easier for you to read, a typed essay or an essay written by a 10 year old by hand. Same thing with the discs. burn slowly, it will preserve your Wii's lense because it has to compensate for less "sloppiness" Really, you probably won't be able to fry the lense... it takes a lot to do it, but taking precautions is always nice. It might be good to note that legit games that you would buy from the store will wear down the lense as well, they are just less "sloppy" because they are pressed, not burned.
