Re: PX-708A and DVD+RW patch

Not to discourage you from trying, but there're certain things that
you ought to keep in mind:

1. read "P.S. non-essentail "rant."" at
2. note that there're now DVD+capable units which terminate write
   requests with "LONG WRITE IN PROGRESS" as well and PX-708A is one
   of them;
3. currently available DVD+RW kernel patch does *not* expect unit to
   return "LONG WRITE IN PROGRESS" and it's not clear what happens in
   such case;

would it write someting on insertion?

2.9MB, which is of the same order of magnitute as internal buffer and
therefore can as well be first "LONG WRITE IN PROGRESS." Other possible
explanations are discussed in "Packet writing on NEC1300" thread at
http://lists.debian.org/cdwrite/2003/cdwrite-200309/threads.html with
http://lists.debian.org/cdwrite/2003/cdwrite-200309/msg00061.html as
