[mythtv-users] pcHDTV and HDTV

[Steele Price]

I'm running MythTV to a Sony Widescreen Tube using an Audio Authority
vga->Component Video transcoder in 720p exclusively, the picture quality is
superb.  You don't need DVI out for a decent picture.
While these may not be cheap... if you want HDTV you don't want to ruin it
with inferior output either.

This is encouraging.  I've been waiting for a card like this for many
months now.  Now that is available and a known commodity, I can start
planning a machine around it.

One question I haven't done much research on, not directly related to
the card but never the less very important...
What output options are there to drive from a graphics card to a HDTV
using component cables?  My HDTV doesn't have DVI inputs, so I need
either a card or converter with component outputs.  If its a native
video card, then I assume it has to be running in the native
1920x1080 interlaced mode?  Etc, etc, etc.  Again, it may not
be a big issue, I've just haven't done the research yet.

Thanks,
Brian
