hey, I just recently harry potter the other day and it came it with superb quality and everything. My prob is that when i play it with media player or power dvd the movie freezes at alternate points and if i move the movie ahead the voice sync goes off for like a min. I know the prob lies with bad frames and such but i dont how to fix it. I i wanted to take out the sound and just add it back to the movie using virtual dub but i dont know how to totally take out the sound of the movie to do it...any have any ideas?
