For the last time, we didn’t cut out the OP and ED. We used something called “ordered chapters”. This means that the OP and ED are in separate files (and are magically linked to each episode so they play normally). It helps to keep you from having to download an extra 100MB with each episode, saving bandwidth and disk space.

HOW TO PLAY ORDERED CHAPTERS:

a. For Windows: Install CCCP. Then, go to combined community codec pack/filters (in case you can’t find this, it’s in your start menu), and select haali media splitter settings. Make sure that “Attempt to open linked files” is checked.
a1. For Macs, download mplayer osx extended rev14 here and download this binary. Install, and check that subtitle scale is set to 100%.
a2. For GNU/Linux, use this build script to get a working mplayer install that supports ordered chapters.
b. Put the episode in the same folder as the OP and ED files. If you do not have the OP and ED files, they’re most likely in the torrent for episode 1 of the anime you’re trying to watch, or on the IRC bots.
c. O?pen the episode using Media Player Classic. It will play normally.

Some people have asked this, and yes, you can rename the episode and OP/ED files and the ordered chapters will still work, as long as everything is in the same folder.
