The message thread about DVD writers makes me think that there are many standards or types of writeable DVD media that not all drives can handle - is this true?
Could somebody compare/contrast the different types?
That PCWorld article I mentioned earlier in this thread has a nice table. The first step is to note that there are three pairs: DVD-R and DVD-RW DVD+R and DVD+RW CD-R and CD-RW plus one single, DVD-RAM which (so far) has no RW sibling. (I include CD's to emphasize the pattern) That article also has a table: Type Can be written to by drives of type DVD-RW DVD+RW DVD-RW/+RW DVD-RAM/-R/-RW DVD-RAM/-R DVD-R yes no yes yes yes DVD+R no yes yes no no CD-R yes yes yes yes no DVD-RW yes no yes yes no DVD+RW no yes yes no no DVD-RAM no no no yes yes CD-RW yes yes yes yes no and with same rows: Capac Cost Cartrige?
