I said the same to Christian.

That one will vanish when Haali's splitter will become the official one.

Indeed it's a big pb. We have told Real about this problem. Not that 
they care about pirate stuff. But in the end ppl will hate them for 
being so close-minded and use competitors instead. I personally won't 
encode in RV until this issue is solved (if ever).

Well, the problem is spreading softwares with bugs (not spec compliant) 
and not being able to fix them (because of Gabest). VLC or other players 
never had any problems with 64-bits floats.

Hopefully once we have the menu done and clean Wavpack support, the 
specs will be frozen. And we won't be the ones to blame if a software 
doesn't respect them.

Things are getting harder on this side. The OGM zealot is still mod and 
alexnoe and Christian are banned. So we'll probably just move somewhere 
else. Users with questions can reach us by so many other means than Doom9...
