sorry, but this is not true. go and get a tascam dedicated cdrw
unit. it works 100% of the time, perfectly, with a s/pdif real time
input. at least, the one i have access to does. it can only do "audio
time" burning, but given the dedicated nature of the beast, thats
ok. i very much doubt that its internal mechanism is significantly
different than the one in my yamaha computer-mounted burner.
the technique to implement this is very simple, and even cdrecord does
it: you just buffer N seconds of the real time source before you start
the burn.
