So actually, this is some very good news. And I understood that the DSP also is used for the MPEG4/Xvid/DivX playback ? And that it also supports other audio codecs than MP3/WMA? Are these implemented in the API of Neuros ? I'll take a look at the source code myself, but as I did this before and didn't came up with anything relevant, I thought it would be better if I asked it here.

The DSP is used for everything DAC-related so that would include videos, yes. And the chip wouldn't have a chance to display full frame-rate video on a TV without using the DSP pretty good.
Lots of the codecs Neuros use are in the DSP parts and they're not provided in source at all.
toffe:
you are right, they have a zen pmc, and the zen m seems to be a creative software, not pmc
my mistake :(

Its definately based on Windows CE (hence the nk.bin and MS dev tools for everything).
PMC is also based on Windows CE, so it may be basically the same thing.
Edit:
Also, heres the nk.bin if anyone else wants a look:
http://www.duke.edu/~mgg6/rockbox/nk.bin
Also, the nk.bin is compressed inside the updater, so don't expect to see ARM in there. Even zipped its still about 10-12MB, maybe more, so almost the entire updater is just the compressed file with a bit of x86 to decompress it and handle the USB stuff I think.

I sincerely doubt it that ZVM is running WinCE. You are right concerning the updater program, but I'm not sure if you read through the epizenter.net thread, cause there has been already some "disassembling" on the nk.bin: it's splitted up in several blocks and those can be extracted.
According to http://libnjb.cvs.sourceforge.net/libnjb/libnjb/HACKING?revision=HEAD(search for 'CIFF'), these files are also (partly) on older Zen's, which means the OS of the ZVM is based on their OS, and (stated in that same file) the OS of a Jukebox is OaSis; I don't know if this is the same on the Zen Xtra or newer Zen's...
Anyway, if you haven't read the epizenter.net thread, plz do it sometime; if you have, srry for bringing this up.

Anyone tried taking out the ZVM's hdd and plugging it using an adapter to a computer?
