I believe what you are expieriencing is this, the extra track is the culprit. Use microstudio and import your tracks when it starts hanging up on the last track, eject the cdg and you will get and error message. You will have a full cdg on your hard drive ready for export to your hoster. If you like put it in your player and time the song if you have another cdg with the same song look how long the song is. Then burn at 1X and eject say 10 seconds after the time is up. If you notice when in import tracks the last track is a few seconds and the last song track is usually way over in time. The 120 cdg I venture a guess is Essentials 1 thru 4? Check them for the extra track such as the E4 disk 30 has a bunch on it, which is advertising.
The plextor and microstudio will do all of the above.
