I've never seen this ZIP file, OTOH I had a deeper look into the "new"

2004, let me guess that the "new" Testsuite just recycles the content
of this ZIP ?

COOL (yesterday it was dead) ... BTW, I'd prefer a TAR or a bunch of
TAR's (per < 2 GiB) from 1'000'000's of single frames to download.

Why "players" ?

5 seconds should fit, maybe time is needed to study the broken look ?
