That would seem to be right. What I'm wondering at this point is why 
there has to be a special bridge filesystem at all. Why can't mplayer 
just read directly from a CD track, regardless of its type, mode, or 
format? I suspect it's just that the vcd:// input module expects 
VCDisms, which probably include the bridge filesystem and other details.

I have used cdrdao to write OGMs straight to Mode 2 CD tracks. MPlayer 
won't read them with vcd://2, but it can read them using the cdfs Linux 
driver. That is a filesytem driver that exposes raw CD tracks as files 
when one mounts a CD. It's not a standard part of the kernel, but it's 
mentioned on the mode2cdmaker page.

Perhaps it would be easy to copy the vcd:// input module and modify it 
to read CD tracks directly. I want to try this because it would obviate 
the need for mode2cdmaker. I could use mkisofs to make an ordinary 
ISO9660 filesystem, then write it to one track and the movie to a 
second, Mode 2 one. Then, it would be easy to make a bootable and self 
sufficient movie CD with eMovix or GeeXbox. Of course, only mplayer 
would read it.
