First, thanks for the replies.
When I look at the capacity of the CD in Nero, it says 79 plus minutes. I burn 78 minutes worth of stuff on it. I am burning Mpg files trying to make a VCD, and maybe later SVCD. They were ripped when they were sent to me by my cousin, who doesn't have a burner.
When I say bad CDs, I mean CDs that burn partly, then stall because of that error message I mentioned. They only play partly. The brand I use is Princo.
