Help!! I'm having a problem. I've used DVD shrink to make a copy of a DVD, and the backup worked fine. then i've burned it to an dvd-r (diva) with Roxio. Now..when i try to see it in a dvd player some parts of the film are missing and the subtitles that i choose (portuguese) are missing too, but if i play the same dvd in a computer using a dvd player the movie is alright and with the subtitles..Can you help me to understand the problem???
