Anyway, Daemon WILL NOT interfere with anything outside of it self
But other stuff might be looking for emulated drives and then fuck up everything like a spoiled brat.
I had games not launch - grab a load of this - because NERO was installed oO
Not saying that's what happening to the OP, but maybe the DVD drive manufacturer is a real asshole? you never know

Anyway, what I would do FIRST OF ALL:
1) firmware update for the DVD drive.
2) get a compressed air can and fffffffffttttt out the disc tray, if it doesnt help, it cant hurt. (try to hit the laz0r)
something else to consider, I thought it was really weird: A friend has a sony vaio with vista on it. the dvd drive supposedly has no drivers installed. at least thats how it looks. it shows up in the device manager, but there is no driver you can remove... at least it seems that way. I know it sounds weird. there just HAS to be a driver.
alright, so he got himself an old program for windows xp, with a nice "VISTA COMPATIBLE" sticker on it. he tries to install it, and the program says "meh, you got no driver, guy, you need to install THIS ONE, here you go". Of course, he clicks accept, because he has no clue about computers, and BAM dvd drive is dead, with the lil yellow exclamation mark in the device manager.
i was able to uninstall that one. but I was not able to find ANY drivers for that specific drive ANYWHERE. even the sony page tells you there arent any for that model. The drive just works without.
So we put the laptop back into factory state, because that was the only option we had, it worked again, he installed the same program again and clicked "fuck you" when the driver installing dialogue came up, and everything works fine now...
I DO think that is majorly screwed. I told him I'm not touching that OS again, unless he allows me to drive a wooden stake through that VAIO.
