I was going to watch some avi files I have of the Simpsons, but it came out in Spanish. Odd! Well when I went to Show Movie Properties I noticed that soundtrack 2 was the only one selected (there were about 6 soundtracks). Deselecting 2 and selecting 1 got it in English, but this appears to have affected all the files like this, and I've played them over and over with out this issue before. Edit: It resets to Soundtrack 2 (Spanish) whenever you change the size or make it fullscreen, AWFUL!
