Additionally, they have zero support for authoring. it was shown at IBC, but didn't seem to warrant much attention.
it's interesting that companies are putting research in to competitors to the two "big guns" but to what avail? Without the big manufacturers behind them...they'll only struggle. Even Nero, with their already-existing hardware/software support, isn't really gaining the traction they thought they'd get, and theirs is a wonderful codec/product.
