Q: What do the different formats, NTSC and PAL, mean?

A: The short answer is that NTSC files are for people in North America, including the United States and Canada. PAL files are for users in regions other than Region 1, such as the United Kingdom and Australia. The long answer has to do with technical specifications of each format. NTSC and PAL have different framerates - meaning a PAL video actually is a bit faster than its NTSC counterpart, making it somewhat shorter. It's difficult to notice unless you have two versions of the same movie (or audio file) playing side-by-side; but eventually you'll notice the PAL version being ahead of the NTSC version. Sometimes the difference is as much as a few minutes! If you find that your mp3 file is constantly out of sync with the DVD you're watching, first make sure that you've downloaded the correct format of mp3 (NTSC for Region 1, PAL for elsewhere) and then check other things, such as the DVD version (Collector's Edition, Director's Cut, etc.) is correct for that mp3 file. These details are usually found on the product page. For more information on NTSC, as well as a list of countries that use it, click here. For PAL information use this link.
