Jordan, we can play read both CDI and VideoCD. I wrote the original code
to read CDI . Brian should be able to step in and explain again.
the videocd format is not really ISO9660 compliant . yes, you can 
read the directory structure however the actual video stream is still
pretty much Phillips format and in fact the blocks are not even 2048.
