Thanks!

Reimar Döffinger told me about the new functionality, and I have 
compiled it up and I am testing it now. However, it appears to drop a 
lot of frames when outputting a 720p 59.94fps file. I'm still an mplayer 
noob, but it looks at least in part that the decklink video driver is 
outputting 50fps. I'm fearful that the new ProRes code is not optimized 
enough to keep up, but this is a capable computer (2 x 2.67 Xeon with no 
other resource hog). Here is the output initially (extra frame lates 
omitted. They come fast and furious).

So what functionality is in the libopencore that will be missing, and 
since the ProRes is newly written code by "Elvis Presley", could "The 
King" be asked to change the license to make it compatible?

Thanks again for your help!
