I have made a quick check:

a) Cylindrical QTVR

1) Thumbnail CubicVR - codec = H264
2) Fullscreen = CubicVR + photo JPEG

CubicVR, Codec = Video Sorenson 3

Personal conclusion:
Cylindrical is unfortunately less and less considered as a standard
to be mandatorily supported by viewer development.
(Cylindrical + Cinepak) combo: As some years ago, 99% of the QTVR
(.pano) were so published on the Web, I believe this is "the" true
legacy available standard and not the reverse!

Michel
