Been using Verbatim DVD's for yours now and never had a problem with them and yes Dell is a bit overpriced on them but still a good buy and I received them the on the day after ordering them with Dell shipping.
The price is higher than its competitior's price. But I choose it based on positive comments. Of course, time will tell how durable the DVDs will be but I take good care of them.
Pros:I have used several of these blank DVDs and haven't encountered any problem so far. Writting was smooth using Vista's program (Yes I haven't installed any program to write CD/DVD, Vista's burn feature is fine for creating data CD/DVDs)
