[mythtv-users] HDTV component output using nVidia 6200 config

[Vinton Coffman]

I got a Leadtek A6200  with component video output dongle for  
Christmas and I'm just getting around to installing it.  I want to  
connect it to my Toshiba 30HF83 via component because I have my  
comcast 6412 dvr connected to the DVI.  I want going to start simple  
with just 480p.  I use two prv-250's capturing at 640x480 but hope to  
get firewire capture working at least for SD and maybe HD if nvidia  
fixes its issues with vblank syncing.

1.  What driver version do you recommend?  Currently running 8178  
with my old GeForce 440 MX s-video out.

2. Do I need a modeline for 480p or does this card only need to know  
"TVStandard" "HD480p" and "TVOutFormat" "COMPONENT"?

3 Will I get black bars on the sides since I'm capturing at 640x480  
instead of 720x480?

4.  Do I need to change anything in mythtv settings regarding  
separate resolutions (the xrandr stuff)?

5.  Can my Athlon XP 2500+ playback HD with XvMC and a driver that  
works with vblank syncing?

6 Off topic: Is a 2.40A GHz P4 prescott 533 MHz FSB 1MB L2 fast  
enough for HD playback?  Its a prescott but does not have hyper  
threading.  I have a spare one here and didn't know if it was worth  
the expense to build up or just start fresh with a new Athlon 64.

Thanks,
Vinton
