Last time I checked, there are at least two formats DVD-RW and DVD+RW, if I remember correctly. I heard that they are not compatible. We are going to purchase a DVD burner. Since the price is stil not very low, we do not want to spend the money on devices which are not compatible with the devices used by the majority in the future.
Sony does a drive that uses all four formats.
dvd-rw is more compatible with existing DVD rom drives and home dvd players. Tha blank media is slightly cheaper.
Sorry - forgot one item
I just bought an NEC ND1300 (OEM) for work, it does all eight formats, cost was around $200. I've not used it yet apart from burning CDs (forgot to buy media, it's on order with our custom printing folks) I bought it mostly so I can copy the MSDN DVDs we get just to avoid scratching the commonly used ones (e.g. VS.NET) and let the developers take software home (yes, I have the twice the number of licenses required, since we're MCPs).
Factor in the fact that the + standard is supported more widely than the - standaard in Europe and Japan, whereas the opposite is true in the US. Or so I am told :-)
Hit http://www.dvdrhelp.com to help you make your decision... they've got a pile of info on what formats are compatible w/ which home players... which is really the point, isn't it?
The + formats don't have that annoying lead-in/lead-out, and at least here in Europe is easier and cheaper to get DVD+R media.
