[PD] [tutorial] creating a DVD with Pd+Gem

[Claude Heiland-Allen]

Hi,

I've written a tutorial on creating an PAL 4:3 interlaced DVD with Pd 
and Gem.

Biased towards Linux, because that's what I use, might work on OS X and 
Windows, I haven't tested.

Still some flaws, notably the lack of spatial filtering before fields 
are discarded (which results in ugly aliasing).  I wrote a C program to 
discard alternate fields from successive frames, if such a tool already 
exists please let me know - I couldn't find one in netpbm or mjpegtools.

Thanks to Roman and Cyrille for persuading me to use the method of 
rendering full frames at double framerate then discarding alternate fields.

Note: if you try it out, be prepared to have plenty of disk space free - 
I needed about 12GB (but I think latest Gem fixes an issue that should 
halve that to 6GB).

Note: you also need to change the path where images are saved (in 
"iris.pd").

Any/all feedback appreciated!

Future plans include adding Pd-generated sound, proper anti-aliasing of 
the video, more interesting video, and better documentation (let me know 
what is lacking).
