'I have wasted a bunch of DvD's on UE2.0- gamers version, all to no avail.'
All the more reason to invest in some dvd rw discs. I gave up on burning drink coasters since I gave up drinking a few years ago!!!
'I have no idea what was causing the write problem with the internal drive.'
Linux is a lot more sensitive to faulty hardware than Windows. The average life of an optical drive is one year and that depends on how much you use it. I only have one just in case I need to rip a dvd or watch a rented dvd. Other than that I don't see much use for them anymore with large usb flash drives so cheap now.
