i was able to burn a couple of DVD-DL last night....schome's zero dvd and STLBlues's shakti disc 2 from long ago...(still had it on the HD for when i got around to buying more DVD9s)i restarted to mac and only ran toast9 to burn...no other apps open. also made sure to move the dvd file to the mac HD(not the external HD)so it did not have to go thru 2 sets of firewire cable. the shakti was first took about 30 min cant remember the file size...about 6.5 gigs i believe but it was a bit smaller that the zero dvd..anyway it burn fine till the very end whan it was all done writing the lead out...it got an error saying "cant complete your request because of mac os error". then the mac proceeded to boot up the dvd and play it. and it plays fine in the dvd player connected to the TV.
the zero DVD(which was bigger in size, not much but alittle) burn fine...no errors at all. i did reboot my mac between burns as well.......maybe some of this will help others....maybe not!?
