[mythtv-users] Re: VIA C3 Deinterlacing and 3dnow

[Larry Matter]

I don't have your answers, but I wanted to share this article which
explains the various instruction sets:

You will probably want to start here if you just care about MMX/SSE:

It seems to me that SSE and 3DNow provide similar functionality, but they
are not the same instruction set.
