Hi. I don't see options Disc-at-once or Track-at-once options in Plextools??!!
Which variant of Plextools (PTP) are you using? "PTP Pro" and "PTP Pro LE" do not support multisession. Only "PTP Pro XL" does.
I use LE. But it's not a question of multisession. When I burn with NERO I can choose DAO or TAO. In Plextools I DON'T SEE SUCH WORDS AT ALL, I DON'T SEE DISK-AT-ONCE, TRACK-AT-ONCE. May be I search badly in plextools preferences?
Plextools only does DAO. There is very little point in TAO in my opinion - it only causes problems.
