It is doable but no a very good idea nowadays. You can get much better recordings internally with vMix

Guillaume

The EXTERNAL button is mainly used to send the output to a "virtual device" which is useful to feed a third-party software like VLC for example.

But it allows also to send the signal to HDMI, SDI or Analog outputs through compatible hardware.

Check :

we use External frequently to route into a BM mini-monitor card, to:
feed projectors
feed a BM VideoAssist recorder
feed modulators (to TV stations xmitters)
send virtual feeds to other programs, like Real Presence, Zoom, etc.

and almost always simultaneously record on vMix too.

Sadly not. And it's not universally compatible with all USB3 ports either!

Will the Intensity Pro PCI work on a 2010 Dell Precision T3500 Workstation that has an ATX Extend Motherboard?

PCI or PCI express?

Anyway: if it has the right pci or pci express port, it will probably work. I don't think anyone here has that exact configuration, but I can't see any reason why it would not work :)

Many have directed and given you help except I never read "this is what you do".

1. You need a way OUT of the computer - This can be an external box via USB or Thunderbolt or an internal card using PCI.
2. If you have an HDMI HD signal out you need a converter box from HD to SD as DVD recorders are SD.
3. Install the converter so that it works directly with your DVD recorder. The PC must have a working output before vMix will be able to use it.
4. The signal would be configured in vMix via the External button. Hit the Cog Pick your Output.
5. Once configured and working correctly(this is the issue I have most of the time) You press the EXTERNAL BUTTON and boom goes the dynamite vMix is being sent externally.
6. Now you Press record on your recorder and you are done.

Remember that SD is 4 times smaller than HD which is 4 times smaller than 4k so by math 4k is 16x the resolution of SD which is what a DVD burner is.
If you want to distribute the content after the show you can always record internally at a higher resolution and downrez in post, aka transcode to a smaller size.
Also if the goal is distribution Black Magic Design has an SD Multi Recorder(I think it does 24 at a time) for people doing HD content at shows.

Hope that helps and please let me know if you have any questions about what I am suggesting.
