RadicalEd0 where are you :p

Tee hee..

OGM = OGG,

OGG is a container like AVI. It was mainly designed to hold xiph's audio codec Vorbis. They also have a video codec in the works. You can store other forms of video in a OGM file however. You can also do more advanced things like embed subtitles and chapters into your files.

It's like AVI on steroids.

To view a OGM file you will need OggDS as well as any codecs the the embeded video or audio uses.

You can get OggDS @

Radical will probably chime in with more info :O Or correct me.

It is the subtitles that interest me. Are they a seperate part of the file, or are they a part of the avi like any other subbed anime?

Well, it depends. I've downloaded some OGMs of Kenshin that have seperate SSA files for subtitles, and then I've downloaded DBZ eps in OGM that have the subtitles directly embedded into them. Best thing about OGM is the ability to have video streams, 1 or more audio streams plus on/off selectable subtitles. No more hard-coded subtitles.

Klinky had most everything right. A more in depth review would be this: Ogg was created by Xiph (opensource company) mainly to store vorbis audio. However, a guy named Tobias created a set of directshow filters which allowed reading/writing of video streams inside the ogg container, which is superior to avi in many ways. For simplicity mostly the people of doom9 tacked ogm onto the end of an ogg file with video and not just audio. ogm is the same as ogg, just a way for windows to play one file in wmp and the other in winamp. Anyway the functionality of the container is like.. infinite, the main advantages to it are:
1. vorbis audio. Multiple vorbis audio streams. and anyone should know that vorbis kicks ass compared to mp3, aac, wma, and much of everything else
2. yeah, built in subtitles. you can mux an srt subtitle file into ogm stuff making it a great way to backup sub&dub anime
3. built in chapter points, making backing up dvds cooler since the chapters are retained.

here's an example of all of the above:
