I see some have already found the normal problems we have just about everytime Apple updates the MOSX. I am willing to bet everyone here has updated to OSX 10.4.8 within the last three weeks.
It isn't bad media or some weird bug with anything any of us are using, since we are all doing the same thing we always do when using this program. It is, however, a normal problem with system updates.
So the ball will be in Roxios court for now until they can come up with the solution....meanwhile, we wait and hope that Toast can take up the slack until the fix is released.
Note to Roxio: hurry please
