ATI AIW X800 XL AGP Breakout connector
 

For the the ATI All-In-Wonder X800 XT AGP edition, do I need the connector that has two threaded connections to screw onto, one with two input jacks, and one with a vga connection. I found 3 different variations of the same plug. Don't know which goes with this card. Thanks for any help. Sorry for confusion in title this card is XT not XL

What each connector does and what are you going to use it for?

For svideo vcr capture I want to digitize some old tapes.

I've scoured some manuals and I believe the one with the vga breakout is the appropriate one for the card.

@supragsx I think that is incorrect.

For your XT (AGP) version of the AIW X800 I believe you need the one in your first attached image. The X800 XT has no coax connections on the backplate of the card but does have both DVI and VGA output connections. So to use the tuner it would have needed a way to connect to a cable or antenna input. Note that the connector in your last image might also work but was sold in europe, etc. so has different style coax connectors.

If you find one of the connectors, you will also need the ubiquitous "Purple dongle" which are readily available on ebay.

Here's a pretty decent discussion on these connectors. If you read through the entire thread, you will find a discussion of ways to connect to the card without the special ATI cables by connecting directly to one(?) of the headers on the card.

More images of your cards complete "kit" when new.

You're correct upon further inspection the manual I found is for the pcie version of the card not agp.

I have that purple breakout, if you need it PM me.
