I suggest you upgrade to Stomp 4.50, as many people's problems are resolved after making the switch. Some people have no luck with with the 1.40 Ritek hacked firmware, plus it screws up your ability to erase dvd-rw, but there is another way to burn your Riteks at 2x and not lose the ability to erase your dvd-rw. Downgrading to
1.31 solves both these problems. That's what I use and it works superbly.
