My blank media experiences
I recently modded my Wii and I thought I'd post my experiences with blank media. I have a NTSC (US) Wii (purchased on the day the Wii debuted) modded with a Wiikey. Here is a list of which media worked for me and which didn't. I burned the images with a Samsung Litescribe DVD+/-RW 18X burner.
Newegg.com - SAMSUNG Black 18X DVD+R 8X DVD+RW 8X DVD+R DL 18X DVD-R 6X DVD-RW 12X DVD-RAM 16X DVD-ROM 48X CD-R 32X CD-RW 48X CD-ROM 2MB Cache IDE DVD Burner with LightScribe and Software - OEM
Did NOT Work:
Imation DVD-R 16X (burned at 2-4x)
Dynex DVD-R 16X (burned at 1-6x)
Verbatim DVD-RW 8X (burned at 1-8x)
FujiFilm DVD-R 16X (burned at 1-8x)
Sony DVD-R 16X (burned at 1-8x)
I've heard Taiyo Yuden discs are great but I didn't want to buy a pack of 25 and find out they didn't work on my particular Wii. I've heard each Wii is different and you just have to keep trying media until you find one that works. Then you just stick with it :)
Hope this helps someone out there.
