SH-S183L problems

i’m having problems burning dvd’s, and i’m not sure what the problem is. dvd firmware or mb bios or both.

i have a evga 780i motherboard with p07 bios and a samsung internal SATA DVD-burner SH-S183L with SB03 firmware

don’t know what triggered it, but it used to burn dvds perfectly. now i constantly get errors. i’m using phillips dvd-r and fuji dvd-r and both did fine in the past. here’s what i’m getting:

“Could not perform end of Disc-at-once
invalid write state
Could not perform end of Disc-at-once”
then i get a write failed pop up window.

i’m making coaster after coaster,
please forgive i searched but i’m not entirely sure if this is the same problem as the ones i ran across searching…

please help
