using imburn is your best bet. you don't have to burn at 4x. i burn all my games at 16x and i never verify. i never have any problems with them. just make sure that you are using good quality dvd's. steer clear of store brand discs. i usually use sony or hp disc's.
Sorry, but I have to disagree with this. I've read multiple discussions about this, so you're not the only one who can burn pretty much any DVD on pretty much any speed and still use it. But others are not so lucky. I had more than a few burns fail on me because I burned it at a speed that was too fast.
Can't say the same for brands, as I just went out and bought the most advised one (Verbatim).
But that aside...no matter what brand or speed...the burn shouldn't fail when verifying. xxdeb1979xx...have you tried running the .iso with dolphin (a gamecube/wii emulator)? If that fails, then the image has a problem.
If that works, it's either your burning program (as said: use imgburn) or your DVD-writer. I really hope you don't have one of those ancient ones without buffer underrun protection, because if so...then burning anything requires a good amount of prayer*. And I would
really advise you to consider getting an USB drive. I normally do that anyway (more cost-efficient in the long run), but with a faulty DVD-burner it deserves even more credit than normally.
Last question: how old is your wii? It would be nice if you could get your burns to work...but if you have a wii that's less than a year old (eg. those black and red wii's), your wii simply won't accept it.
*seriously...my first CD-burner was so cheap I almost ended up paying more on broken CD's than on the drive itself
