dvdrom not recognized, showing as cdrom after boot

My installation cd is a dvdrom and the system sees it as that until ubuntu has loaded, then it's just a cdrom and is unmounted. This happened after all updates where install, but is not the only issue resulting from updates. Also having video card driver issues, the hardware device manager allows me to activate the nvidea driver but only goes as far as the file search screen and then stops and doesnt activate but it says the driver is there. I had a similar problem with errors from updates with firefox but managed to bypass that and reinstall firefox which allowed me online at least. The only other hardware driver i'm running is for my wireless network card.
