Why Session Fixation Error Writing Lead-Out?



I'd like to know why I frequently get "SESSION FIXATION ERROR WRITING LEAD-OUT" messages when using Toast 10 Titanium to burn dual-layer DVDs from VIDEO-TS folders. I see something like:


The drive reported an error:

sense key=MEDIUM ERROR

sense code=0x73,0x03

the disk failed to be written


I'm not sure those hex numbers were the actual sense codes I'm seeing, as I copied those from another post I googled online. I don't know how to locate Toast's logs to check.


I've been using Verbatim DVD+R DL media in a Samsung DVD writer that shows as "TSSTcorp CDDVDW SE-S084C". Its USB cable is plugged directly into my iMac running Mac OS X 10.5.8. I have no known issues with that Samsung optical drive besides its failure to reliably burn DVDs.


My memory is not reliable enough to be sure I haven't seen similar problems with burning single-layer DVD media, as I've been coping with what seems to be a "hard problem" with my iMac's internal optical drive's focus servo, causing it to be unable to write dual-layer DVDs at all. Hopping around trying to burn movie-copy DVDs in a timely fashion for transmitting to a hospitalized friend has resulted in my not being sufficiently attentive to what problems have happened in what specific situations that have left me with so many "expensive coasters" in the last week or two. Does anyone have any idea what I should do to nail down and eliminate my DVD-burning problems in the immediate future? Thanks in advance ...

Check to see if a firmware update is available for that Samsung drive. Make sure it is connected directly to the Mac and not through a USB hub. Try choosing Save as Disc Image and then burning the disc image using the Image File setting in the Toast Copy window.
