In short no there isn't as the firmware is encrypted in the drives that ship with the Xbox and so far no-one has successfully examined it to figure out how it works fully, at least from what I know..
You can read a discussion on the topic below;
I had the same drive Philips drive it's a bit of a flaky reader then again not all Xbox DVD drives are the same some Philips drive are good & some bad it's a luck of the draw.
Your best bet would be to get your hands on the Samsung or Thompson Xbox DVD drives, various speciality console on-line stores sell them, these should be better readers then what you currently have.
Their are a few other things too but more messy and require a lot of tinkering for example you can hookup a PC DVD drive but it will only play movies, check out Xbox scene.com for tutorials.
