strange problem after burning T_T

i ran into something strange with nero 6




i was burning a dvd+r with nero, when the "progress status" bar reaches 100%, the "used read buffer" began to drop as usual, BUT insted of dropping all the way back to 0%, the bar stopped at *2%*.


then the drive do the "lead out" thing and happily tells me my burn is successfully completed. at this point however, the bar finally drops back to *0%*, but i'm very worried since the burn is already completed, i went to test the dvd, it seems ok and is readable, but i'm still very worried.



-why didn't the "used read buffer" bar drops all the way back to 0% when the "progress status" bar is 100%? why did it stay at 2%?


-does this mean my burnt dvd is no good? has it become a coaster or damaged?





thanks for the help.
