I've a weird problem! I captured, edited and authored my friend's wedding movie with Pinnacle Studio 10 (with the last patch) and it was played fine by my previous home theater (PANASONIC). But in my new home theater (PIONEER HTZ767) and my LG DVD player, it is played with double speed and sound is a loud screamy noise!
I copied the DVD to HDD and reburn it on another DVD, but same problem exists.
You think what's the problem and solution?
