Cuda 2.1 questions? multicore version.. NVCUVID missing form SDK

I read a while ago that NVIDIA announced a multicore (CPU) compiler for CUDA 2.1 in NVISION…

Since CUDA 2.1 beta has been released without support for it can we expect this anouncement to be true/ up to date and a multicore version be released in a second beta or in 2.1 final version or it has been delayed to next version…

Also what about NVCUVID not appearing in SDK 2.1 beta… I said that because using NVCUVID from SDK 2.0 with CUDA toolkit 2.1 and 180.60 drivers hangs my computer in XP32…
I suppose it will be there in 2.1 final…

Also can we expect an linux port of NVCUVID now that VDPAU is released for Linux and variants…

And what what MAC NVCUVID support now that macbooks support also video decoding on GPU…
Thanks…
