Perhaps.  But I don't think it needs to be "universal".  Our problem is
simply getting the HD signal from the component outs from the STB
converted to a digital stream that Myth can use via firewire (and I'll bet
that Myth isn't the only application (Linux, Windoze or otherwise) that
couild benefit from this).  One could certainly design something that
changes "anything in Column A" to "anything else in Column B", but THAT
would be prohibitively expensive.

Again, we don't need to do that.  Whether what we NEED to do (as above) is
illegal or not is hard to say for sure (I'm not a lawyer)...I would have
thought that simply playing a DVD that I'd paid for on a Linux box would
be quite legal, but M$ and Hollyweird don't seem to agree with me.  This
is a similar issue - being able to view content that we've paid for in the
format that we've paid for.  One would think that's a no-brainer, but that
may not be the case, here in the good old U.S. of A.

Nonetheless - I'd be the first to buy one of these devices when they
become available, as long as it's not insanely expensive and the output
quality is equal to (or at least close to) the 1080i that's coming out of
the STB.

$0.02 worth...
Bob
