It's utterly stupid to do this, there is nothing to prove -- yes, you can
decode the stream, them shove it back into something that Myth can accept.
Why bother? You might as well use the A/V inputs on a standard WinTV card.
The proper way to do this, does NOT require a 'rewrite' of MythTV. As
Isaac has stated before, you simply need to add support for MPEG(1/2)
input streams. From what I've been told, it wouldn't even be terribly
hard, it just needs someone who can wrap their brain around C++ and
NuppelVideo. Please, don't waste your time on such a horrid hack that
does no good.
The only other modification you might need is the storage format, I'd hate
to be getting a high quality MPEG-2 stream only to waste CPU re-encoding
it into some other format.
