Reddit mentions of CE Compass 4 Port 1 in 4 Out 3 RCA AV Audio Video TV Box HDTV DVD PS3 Splitter Amplifier Switch

I recently started recording matches from my crt.

2 things required for my setup to record. 1) must be using composite video 2) must have a non-apple laptop to record with.

Get 2 composite male-to-male cables
Get 1 powered splitter (this one works well for me and cheap)

Get 1 gvusb-2 capture card. This thing records at 60 fps and perfect (composite) quality.

Keep in mind that composite video is not pretty, you would need to have component cords to have it more like streams. But this will definitely cost more than $80 to record component.

The GV-USB2 is probably one of the best cheap cards out there. If you want an example of the quality, here's a recording from back when I was using it. I'm pretty sure it can look even better, as I was only using the RCA cables, and not the S-Video input. Just make sure you get a powered splitter like this or this (for S-video) so you can send the signal to both the TV and the recording device without lag.

Just make sure you set the device up properly and use some kind of deinterlacing. For ease of use I'd just recommend using the built in de-interlacing options in OBS.

Edit: If you're short on money and don't want to spend extra on a splitter for live capture, then you can just save your match replays using Legacy TE, and then record them through the recording device using your computer screen to navigate the menus. This requires extra work though, and it can be easy to forget to save your replays. I'd just recommend getting the capture device and the splitter so you can record it all in one go.

All you need is one of these. I have a small CRT I like to use next to my HDTV, but my friends can't stand it for watching me play so I split the video like so.
