I was printing on Taiyo Yuden DVD-R+ from Meritline and was very pleased with the results. They had a glossy surface which rendered colors very nicely with good saturation and "pop" (I was using an Epson dye based ink printer like your Canon to print them). I also printed on some Verbatims with matt surfaces that were not as nice, looked sort of dull and lacking saturation (I think they were CDs not DVD's).
