I'm new to conversion/burning of DVDs although I have a lot of experience with VCDs. Just got my Pioneer AO6 burner and using included Ulead DVD Movie Factory to convert and burn AVI files to DVD. The first one I did worked fine: it was an Xvid/ Mp3 encoded AVI file The next one was a Divx/mp3 encoded AVI file. On this one, the sound would not play on my Pioneer DVD player, nor on my computer with "Windows Media Player." However, the sound DOES play using the "Power DVD player" that came with my Dell computer. What's going on here? [/b]
