[mythtv-users] Best graphics card choice? (HDTV and regular)

How hard was it to make the sync converter? I have been looking at this,
but the parts are so obscure (on the schematic that I have) that it
seems like it'd be worthwhile to spend the 100usd to get one

I'm not using DVI, but for my PAL TV I'm using the plain onboard VGA
with 
no TV output, a home built sync converter (converts the H/V sync into a 
composite sync that the TV can use) and some custom modelines to drive
the 
VGA output at PAL resolution.  The picture quality I get out of that is 
excellent since it's RGB with no other signal processing hardware
between 
the PC and the TV.  I just need to sort out syncing the Myth output with

the VBI so that I can run the system without deinterlacing and with no 
tearing.  ATM the only problem with this method of outputting to the TV
is 
that Myth will only vbi-sync with Nvidia cards, but the Nvidia drivers
are 
broken and won't do interlacing so you can't use an Nvidia card.
