PowerMac 8500 AV Card

I was recently able to buy my dream PCI PowerMac, the 8500! It works great, although I can't for the life of me figure out how to use the AV Capture Card. My first question: Is the television connected to the composite video output supposed to mirror the monitor attached to the Mac's DB-15 port? Second question: For some reason, instead of starting, Apple Video Player says that the Video Startup 1.7.3 extension needs to be installed and the computer needs to have video capture hardware (both of which are true for this machine). I feel like both of these issues are occurring because I'm missing an extension/driver/etc. although I'm not sure.

I'll note that the only changes I've made with this so far are doing a clean install of System 7.5.3 & upgrading Apple Video Player and the Video Startup extension to 1.7.3 (stock Player version bombed while starting). Also, my primary monitor is running at 1024x768 @ 75hz.

Thanks!

As I recall, no, unless there was a mirroring setting somewhere which I don't recall.  The output mirrors what would be in the video software application's window.  So, you could connect a VCR to the output jack and see in the application window what you're recording.

I'm going from memory though.  I have a 7500 but it's been ages since I've done any video work with it.  (I used Adobe Premiere back then.)

Input and output are stuck at up to 640x480 or something like that on the A/V in and out and you need to have VRAM installed on the motherboard (either 2 or 4MB) for that to work. You can use other apps instead of the apple one but the control panel does need to be installed.

As I recall, 640x480 was high quality video back then.  You could output through the s-video for S-VHS quality recordings.  Then you could create your master tape in S-VHS and make your VHS copies from that which would give you high quality VHS videos without the deteriorating quality from copying from VHS to VHS.
