DVD-ROM manuals

[Tihol Tiholov]

Greetings all,
I'd appreciate some details and people's opinions/satisfaction re: using the
electronic manuals from Bentley.
1. Can one play the DVD-ROM on any windows computer like a regular disc or
is an internet connection required every time the DVD-ROM is used?
2. Is the purpose of the internet connection mentioned just for content
updates or to verify the software ownership or ... ?
Any other thoughts about this welcome.
Thanks,
