What is HighMAT?

Hmm... the highmat site is very unclear about what the format actually is despite all their marketing bs. Am i correct in understanding that it is simply just a file system format and that its not converting my mp3s, etc. into another proprietary format? Also i saw a mention that Highmat support Mpeg-4 formats, does that include aac? Maybe I'm missing something thats right in front of my face but they could do a much better job of explaining the technology.

There is a lot of marketing crap around about HighMAT, but it is simply a file system. 

Included in the file system is a "metabase", or database containing metadata from/about the files on the volume; think of it as a "catalogue".  By examining this metabase, volume reading devices will be able to more rapidly inform software what is on the volume (without the software having to open each file and retrieve the metadate therein) and physicaly where it is. 

The HighMAT file system drivers need to be able to read the metadata from the media files to populate the metabase, and only certain media file formats are currently supported, but more are being included over time.

Well i played with it some since xp can burn Highmat discs and my panasonic dvd player is compatible with it too and i am afraid to say it seems like nothing more than more of the same from MS. I tried a disc full of mp3s all tagged with id3v1 tags, one of them with a cover art jpeg in the directory. The interface it creates when playing it back on the dvd player works much like media center and does a good job displaying the meta info about the songs, however my biggest complaint is that it considers any mp3's with a bitrate over 128kbps to be "incompatible" and transcodes them to 160kbps wma files. When using the xp cd wizard you have the option not to convert the "incompatible" files however then it will not include those files in the metabase and simply doesnt display them at all. Sorry, but i am not one of the deaf few who consider 128kbps to be "cd quality" and unless i can play back my mp3's at full aps quality, ill do without the metabase for now. I give MS a C- for effort.
