As far as I know, DVD ROM discs are supposed to play on every DVD player of the market, including PC DVD drives. I have an ASUS DVD drive (E616), a Plextor DVD+RW drive (504A) and a cheap standalone DVD player.
Up to now I could play every disc in market, but a specific DVD Video disc could not be read at all by the ASUS (mine and a friend’s) or had several problems with the Plextor (it locked/freezed occasionally). It played normally on the standalone player though.
The DVD was the “Catch Me If You Can” (region 2 - Europe). I noticed on the disc a couple of rings, similar to the Laserlock protection for CDs. I finally was able to rip (after 3 partial tries) the DVD and watch it from the hard disc.
Do you know what is it all about? Is it legal to make a DVD that can’t play on PC DVD drives?
BTW: I downloaded for the occasion AnyDVD and used it with everything “on” but without result, at least for the ASUS drive.
