Right.
You would know that it's suspicious to talk about a live DVD when there is a read error.
If he has an external DVD drive and /dev/sr0 means he doesn't have an internal DVD drive....
I'm a little confused about all this... - I had an issue with the Live TW dvd NB. dvd's get corrupted if a fly unloads on them so it's NOTHING unusual. If I haven't seen this a thousand times then I never have. I just take out the dvd and rub it on my T-shirt. Guru-level wisdom even says to rub it (now let no one 'go off' on any tangent here) linearly and not in more circular like patterns which leave scratches more likely to derail the read. - you suggested two tests to try - I did the dd one and the result was negative - I haven't done the other yet because I haven't had time NB. I will do that tonight and I have a hunch that all tests will prove negative because as I have suspected since the beginning my problem's roots are in the nvidia card/driver drawer and nowhere else, a dilemma that is now terminated as far as I'm concerned.
Best Regards.
