I've had stellar luck with HP, Sony, Maxwell and ahhh!! I see a trend here. The "names". That is, nothing but the names we know.

I can't tell you how often people show me a DVD that won't read and it's covered in fingerprints or scrapped.
I have storage on external hd and backup on another external hd, but I still want to put everything on dvd disc or something, as well. Can anyone recommend a reliable brand? How many gigs can you get on one disc these days? The one's I've been using are 4.7 but I would like more.
