|No I did not use PureVideo, but 'NVidia DVD Decoder' - as suggested by the site I consulted.|
What I mean by #17 is that, so long as I have access to one ODD, I am satisfied.
Since there are two ODDs in the PC, I have the luxury of choosing WHICH to use.
I would like to KNOW why the O/S will see only one.
Similarly I would like to KNOW why what worked once, wont keep working, namely the NVidia DVD Decoder played DVD perfectly, ONCE but NOT AGAIN.
I tried the NVidia on a second clone with the same result - ONCE ONLY.
