Thanks for the large number of interesting posts to this question.
The one thing which strikes me most after reading through all of replies, is that the large majority of people are interested in recordable DVDs because they want to burn movies and watch them in a set top box.
For this DVD-R is to me the number one logical choice for all the reasons mentioned above (cheapness of media, more compatibility, etc).
However, I am surely not the only person to see the great potential for using DVDs for backup purposes in small companies. This is why I purchased my DVD+RW drive, and I have no plans to even think about using it to burn movies for the foreseeable future.
Therefore, what I am looking for is the utmost in reliability and data integrity above anything else. Every article of information I have read indicates that DVD+RW is the better format for data storage, which is why I went out and bought a DVD+RW drive and a stack of high quality media to go with it.
Compared to tape drives and cassettes, providing your storage requirements are met by 4.5 GB limit, DVD+RW is great choice for backing up and archiving data. I use Aheads InCD to drag and drop backup files over to disk. This has worked faultlessly on my machine for many weeks.
So long as DVD+RW media is readily available, I'm happy. I don't care one bit if it costs a few pounds more than DVD-RW, being as I am saving a fortune not having to use tape backups.
Maybe no one format will win the war... Maybe it will be the norm that all future DVD drives support DVD-R/W for burning movies and the "technically superior" DVD+RW for data.
Surely, as a knowledgeable technical community, we should all be supporting DVD+RW as the best choice for data storage?
Personally I don't feel I would be happy backing up my companies data onto DVD-RW, a format which sounds to me like it was rushed out the door a long time ago before much thought was given to reliability, random access, background formatting, loss-linking, Mt Rainer support, etc.
