WMF media type???

[Hyper Shinchan]

I've found on internet a long of time ago a pair of strange mp4 (don't worry they aren't copyrighted movie or this kind of stuff, it's just a pair of short funny clips ). They are pretty hard to open with a lot of players and filters, and the better option seems to be the old philips player. Now i've tried to dump them and I've found that they have a strange wmf media type. What kind of file is it? Do you know it?
This (http://digilander.libero.it/Hyper_Shinchan/Doom9/Breath_info.zip) is the dump made witht the -diso switch of MP4Box

if the files are old i would assume they have been produced with a tool not really writing compliant mp4 files

maybe you can extract the streams to raw and remux to a new .mp4 for getting a correct one

Of course :). i was trying to understand what kind of mp4 is it. But it's not so important, in the end.
