I have Power DVD and if it fails I uninstall and reinstall that.
VLCPLAYER can play VOB files if you need a replacment.
i installed a trial veriso of nero 7 a wehile back, then i bought a new drive that had nero 18.104.22.168. this allows me to do lightscribe label ing BUT whenever i use power dvbd to open a vob file I get this error message about fatal error, installation corrupted, reinstall nero-- i have uninstalled the old nero and reinstalled twice, no luck. do i need to excise nero 7 out of my registry? (i don't think this oem nero disk has a dvd viewer (showtime) in it . . . would be nice to watch dvd's again --fj
