To say a few words about 0.1:

First: This is a very early test version, it can quite possibly blow up.

It comes without any configuration, and its only tested on VP4 (Fermi) hardware.
In the future, you will be able to configure things like:
- Use Stream Aspect Ratio (currently always on)
- Which Codecs should be active
- Should Deinterlacing be performed (currently always in "adaptive" mode)
- And whatever i can think of.

Also, it only supports NV12 output. This might change in the future, but any conversion of course gives you a performance penality, and NV12 is the native format of the decoder.

Oh, and if you're using it together with LAV Splitter on interlaced VC-1, make sure to disable the VC1 timestamp correction in the LAV Splitter settings. The next version of LAV Splitter will have this decoder added to the auto-detect mode.

BTW, if anyone is good with assembler, i could need some asm function which changes the stride of a NV12 image. My C implementation is probably quite slow.
