i got an answer from erightsoft for my e-mail (you can see below) and e-mailed back explaining that things are not completely as they know... i kindly asked them to add ogg support besides ogm and mkv since it is recommended container by xiph.org...
they offered me renaming the extension as .ogg as you can see below . so it is also possible that they might be using the name ogm instead of ogg... but it is not right anyway, i explained them so...
but i will ask you one thing: is it just the same as original ogg if i change the extension of a ogm to ogg... is there a way to identify if the container is originally an ogg or ogm for the END USER...
another important thing is that subject about ogm in wikipedia can be misleading... i first read about ogm at wikipedia and thought it was also supported by xiph.org. someone who knows more than me about the issue should change it on wikipedia. as you can see from the answer to my e-mail from erightsoft below, they know about ogm from wikipedia, too...

Subject: Re: super ogg support
Thank you for your email and your interest in SUPER(C)
The term "Ogg" is commonly used to refer to audio file format Ogg Vorbis
The term "Ogm", means Ogg Media file, is a container format (for video, audio and subtitle streams)
SUPER(C) supports both of them as input and as output..
You will find the Output container for the rendered Video/Audio Ogg Media file under: [OGM]
and the the Output container for the rendered FLAC or Vorbis Audio Only files under: [OGG (Audio Only)]
Once you render an [OGM] Video/Audio Ogg Media file, feel free to rename the extension to OGG if you wish.

Subject: Re: [theora] ogg, ogm or mkv
it says this on changelog
[ADD] OGG (Audio Only) Output Container, rename the old OGG(Video, Audio) to OGM(Video, Audio)
[ADD] Support to encode, play and render vorbis (very high quality) with the OGG (Audio Only) container
i don't think they are using it with wrong ext because there is also an .ogg option besides .ogm, in the container format list but it is just for audio!. it says "ogg(audio only)". but in the previous build there was an ogg option for video that i have been using and i cannot find the .exe for the older build anymore, anywhere and i have written to them about my disappointment not seeing ogg in the video container list...
mkv and ogm are offered for theora on the new build....
by the way i have just discovered your http://lists.xiph.org/container/ page, which has a good explanation on the issue, on xiph.org from a link from another website. but i didn't see any link to that page from your website even though i have been checking your website for months. if there is any, it must be "hidden":) and people cannot reach it easily, just to let you know

Can you send a link to information on "super" and it theora support?
"Ogm" for theora is very unusual. Are you sure they aren't just using
Ogg/theora with the wrong extension (ogg and ogv are correct). Can you
point us to a file from it?
