I can't play dvd in pc

I've got a dvd disk containing a series-movie consisting of 5 parts.
I've found files *.vob, *.bup and *.ifo on it. Unfortunately, disk
cannot be played in my dvd-drive "LG" automatically. I can play some
parts only. In the rest files show time to play is 0, athough file
extension is more than 1GB.
Can anybody help me? There is everything OK using dvd-player.
