It seems it may depend on which DVD and which DVD drive is available. On my w2K and other machines I have, some DVDs, some movies, the DVD drive will read and will play (using VLC). However, some disks that can be read by the drive won't play in VLC, but can be played using other media players. And some disks (notably the newer commercial DVDs) cannot be read at all much less played on any media player on some machines.
This is true on more than my Panasonic toughbook CF50/51.
That is, VLC will run to play streaming media and home-brew DVDs with w2K for sure. Disks like "Black Adder" (older encoding format?), for instance, won't play using VLC, but will play using other media players in w2K (and Linux). But, the newest DVDs aren't even recognized on some machines
So, I am surmising that even if VLC worked to play the newest DVDs on other systems, it probably won't work on my machine (unless I could do something with how my DVD drive reads DVDs.) Bummer. It would be nice to have VLC read some (other) disks that my drive does recognize, however. So I will post here again should I find out how...or if anyone knows, if anyone could help with this specific problem, I'd love to hear.
Thanks again for all help
