I'm prettymuch through a batch of these
http://www.dabs.com/uk/productView.htm?quicklinx=32T2 and had no probs with them from my writer and player.

and then i have tub of http://www.play.com/play247.asp?page...G&title=146871 to try.

Both came in at £18 for 25 DVD-Rs. Hopwever, I've just seen that dabs have theirs at a new lower price. £13 for 25.

Both reputable companies I;ve used on a number of occasions and happy to recommend.
