I have been using Taiyo Yuden DVD-R 8x Full-Face Printable blank media without problems. I always save my project as a disc image and burn through disk utility at 2x.
I have just purchased the new Taiyo Yuden Watershield F-F Printable 16x DVD-R but the slowest I can burn these is 4x.
I am worried about compatibility issues is the difference between burning at 2x and 4x that critical?
