Maxell is good media but I never heard of BenQ producing media, drives yes, media no. Try to pick up a small pack of 10 of FujiFilm Media 8x, but it must be Made in Japan, not Taiwan. That will be Tayio Yuden (Made in Japan only) considered to be the best. The stuff Made In Taiwan is not Tayio Yuden.
I don't know if you have Best Buy stores in Canada, but here in the USA you can get the 10 packs.
If that doesn't solve the problem you have other issues, like adding software that you didn't have when the program was working properly.
"This way they won't sit around for too long. Would that make a difference"
Should make no difference with quality media, but heard horror stories about the cheap stuff. A disk that worked fine 6 months ago no longer plays because the dye deteriorated. Use common sense when storing, away from heat and humidity.
