Maplins are selling 100 DVD-R or DVD+R for £12.49 at the moment. MrDVD I think was the brand - not sure if they're better or worse or what. They all work the same for me!
There is absolutely no competition - verbatim are far far better than mrdata (or anything else).
If they have japanese manufactured verbs then they are TYG03's, which are some of the best discs available. if they only have taiwanese produced then they are MCC03RG20 which are still very good discs. There are also some made in india, but they are best left on the shelves (MCC03RG20 too, but made by MBI). They are all code 834712 on the website, you'll have to hunt through the boxes in store to find japanese/taiwanese.
288554 on the website are DVD+R, so they will be YUDEN000T03 for japanese manufactured and MCC04 for taiwan/india. again, take taiwanese over indian.
