Followup; after visting Stephan's site at
http://kbs.cs.tu-berlin.de/~stewe/vceg/, I may be confused, but I still
think not. If you visit www.vqeg.org (mirrored at http://media.xiph.org)
you'll find that the sequences you compressed AREN'T there. The VQEG
sequences are D1 (both PAL and NTSC) resolution and have file names of style
srcXX_ref__X25.yuv....I also used these in my project, and they're public.
Based on the names and resolutions of your files, I think they're actually
MPEG-4 standards committee material, which as I mention below is NOT public.
I've copied Stephan on this email and perhaps he can clarify
