I can burn to a DRX-500ULX and a Pioneer A03 concurrently with RecordNow Max, no errors. What is your opinion on diasy chaining another two or three 510s to the DRX 500? I don't know enough about 1394 limitations to make a decision and sure would welcome advise.
Well, I called the Sony Professional support line and learned the 510 comes with just one 1394 port, making daisy chaining impossible. However, the 500 I already have can accomadate one 510 and the 1394 on the Sound Blaster Audigy which is on a different PCI slot can take a seccond one, making it possible to burn three DVDs with this clunker concurrently. Was hoping to get some help here but the post was certainly far off topic and I thank the regualrs for not flaming me for it.
