[mythtv-users] What to do with playing HD on 'normal' TV?

[Chad]

Hello!

I've got a Home Theater that I use to watch my "shows" (CSI, Las
Vegas...) in High Def.  I've also got several other 'regular' TV's
floating around my house in various places.  1 of these TV's is so old
school, I have to use an RF Modulator to get a computer to hook up to
it via a composite output on a video card.

So my question:
What does everyone do about this?  I obviously don't need HD output on
this 27" dinosaur, and I also don't want to have to get FX5200's for
every Myth system I build.  Is there another option I'm overlooking? 
Can you maintain 2 versions of the same show on the same MythTV
network?  I would be willing to do some excellent symlinking and
create Recording Groups that match up HD with Recording Group High
Def, and LD with Standard Def (Low Def I call it :D ), but not sure
how I would work it.  I could record the 2 versions of the show
simultaneously, one with my HD3000 and one with my soon coming
PVR-500, but that seems less intuitive.  I'd think something more
along the lines of:
Stream to disk via HD3000, fire up mythtranscode, put transcoded file
in seperate LD directory, and somehow get the regular frontends (not
the HD one) to see the LD directory instead of the HD.

Still, not sure how I'd do that or even if it's workable.

Any ideas, anyone else running into this "problem"?  I know, it's like
that episode of Friends where Chandler goes off about "... and my
wallets too big for my $50's..."; but nonetheless, it's a problem I've
run into ;-]

Thanks!
