Please log in for more thread options Paul, I don't think my experience is all that atypical. I'm in another
thread that has some philips engineers in it. They say that the issue
is laser diodes in cheap (under $50) DVD players, and that high failure
rates are not uncommon. Apparently laser diodes get tremendously hot in
operation and lots of the cheap ones fail from thermal stress. I do
agree that some will last many years, but most of the ones I run into
are "cheap" (regardless of whether they came with the computer or were
bought later). I have had good luck with Pioneer (my preferred brand),
and also Samsung. But some of the cheap brands and the unbranded stuff
has been just horrible.
