[vox-tech] CDRW Buffer Memory

[Peter Jay Salzman]

right, but that was my point -- using the fs argument sets the fifo
buffer.  but clearly you can't use more cdrw memory than the drive has.

rusty, i'm pretty sure matt is correct here.  cdrecord probably queries
the drive for its internal memory.  or perhaps it doesn't even need to
know this information.  it just streams the data at the speed which you
specify (i *know* that the max drive speed can be queried).

in any event, as matt pointed out, i think you want to set your fifo
buffer if anything.

btw, the cdrecord man page talks about this very issue.  do man cdrecord
and look at the first occurance of the word "interal".
