The reinterlace behaves just like the tinterlace and in terms of fps is 
basically the same.

The ASM Opts are used with reinterlace only in case of CONFIG_GPL enabled.

There are two new modes, MODE_MERGE_BFF and MODE_MERGE_TFF for which I 
have documentation.

Also reinterlace processes the planes of a frame in separate threads.

I've tested it with diferent video formats, and the outputs are correct.

Previously there have been acceptance for using some methods form 
tinterlace. Those methods have nothing to do with old, GPL licensed 
code, and are doing some trivial stuff. One can check thread starting at
