[mythtv-users] Mechanical cable splitter

[Josh White]

haha...well done.  You didn't answer my question.  Is it possible to make
such a thing work in the example of connecting a PS2 to a computer monitor
via a PVR-250 (like in the example from the post above mine in the thread)?
And while I didn't say it explicitly, I was thinking that the DVR portion
could be recorded/written as usual, but simultaneously, same feed could be
piped directly to the display (which could be a TV, a monitor, projector,
etc).  Certainly, it would require significantly more CPU cycles on the part
of the backend, but would it be possible? Of course, you could also add a
frame grabber card that would only be used for live tv, saving your PVR-250
for recording duties.  There would be no need to save the frames in such a
case if you're recording for the sake of the DVR, so those frames would only
go to memory and that would be it.  The benefit of such an arrangement would
be that you would still be in the same environment (the Mythtv environment
that is) and if you wanted to rewind, the system would simply switch to the
recording.  One of my wife's gripes is that the lag in changing channels to
too great for her (and she insists on watching liveTV still, but that's
another story)  One of my frontends doesn't involve an actual TV at all, so
that's where this could have relevance.

BTW, when I had a Time Warner DVR, I did have "instant response" AND a DVR.
Just because a typical MythTV setup doesn't offer that capability, doesn't
necessarily mean it is impossible or undesirable.  Is anyone apposed to
having both?  Like if you could have both, but simply turn it off with a
check box, would you turn it off?
